How a Running Shoe is Made

How running shoes are made

How Running Shoes are Made

How running shoes are madeAll running shoes are made by the cold cement construction process. If you want to learn how to design shoes you need to know this basic shoe making process.   Cold cement is the modern updated style of shoe construction.  Due to the low temperatures required for bonding the upper to the shoe sole, it allows the use of modern lightweight plastic, foam and mesh materials.  Every modern high performance running shoe is made by this cold cement process.

Running Shoe Upper Stitching Process:

How Running Shoes are Made-cutting DiesWhat are the best materials for running shoes?  Most running shoes are constructed with breathable knit Polyester or Nylon mesh. Knit fabric allow the material to smoothly follow the last curves.  Running shoe uppers often with PU leather reinforcements.  Pu or synthetic leathers are great for running shoes as they have some stretch and are damaged by water.  The classic running shoe is made from suede with some mesh inserts.  While suede is comfortable and conforming, it’s not weather resistant and it’s very heavy when wet.

How Running Shoes are Made- CuttingThe pattern parts for the shoe are made into steel cutting dies.  A cutting die is required for every part and every size.  Each shoe part is cut from rolls of fabric or from leather hides.  Fabric parts may be layered so many can be cut at the same time.  Leather parts must be cut one by one to avoid having scars or other imperfections in the leather show on the final product.

The factories cutting department cuts all the parts for each running shoe, then gathers the parts into kits.  One kit for each pair of shoes.  After several hundred or even 1000 kits are complete they are passed to the stitching department for assembly.

Running Shoe Production Assembly Process:

shoe making for beginners pdf, how to make shoes step by step, shoe making kit, how to start making shoes, how to start making your own shoes,

The running shoe upper is prepared with the strobel bottom.  The outsole covers the edge of the upper so a strobel bottom can be used to make the shoe lighter and more flexible.

The running shoe upper is steamed to soften the materials and the last is inserted and pulled tight.   Once the last is tight inside the upper a second lasting machine pulls the heel edge.  Once the last is secured inside the upper, temporary shoes laces are pulled tight, and the upper is cooled which allows the upper to shrink and fit tight to the last.

The shoe may have a plastic or fabric part installed on top of the tongue to protect the surface from damage and drift during the lasting operations.

While the upper is being lasted, the sole unit is being prepared. In this case, a rubber sheet sole is combined with the EVA foam cushioning component cemented inside. This is done in a separate process that’s called stock fitting.

Running shoe midsoles will be made from weight EVA foam.  A thin layer of rubber will allow the EVA to flex, but protect the midsole from wear.

Now that the upper is lasted tightly and the outside unit is compete, the two pieces come together. The rubber sole unit will receive coatings of primer and cement. The outsole will get its own special primer designed for EVA and rubber. The shoe upper is also prepared with its own special primer and cement.

shoe making for beginners pdf, how to make shoes step by step, shoe making kit, how to start making shoes, how to start making your own shoes,

After the contact cement and primer have been completely dried in the heating tunnels, the two pieces are joined together by hand. A skilled worker aligns the upper and outsole together then places the shoe in a hydraulic press.

The running shoe will have 3 pressing operations, usually all done with one machine: a vertical press, toe and heel press,  and side pressing. This insures full contact between the upper and outsole uit. Once the shoe is pressed together it’s often put in the cooling tunnel to set the glue.

After the cooling tunnel, a shoe de-lasting machine is used to push the last out of the shoe without wrinkling the running shoe upper.

Now the running shoe is complete!  At this point you can insert the footbed.  The footbed may be molded EVA with a fabric cover or flat sheet cut foam.  The flat die-cut footbed is usually cemented inside the shoe, while molded footbeds are most often removable.

The new runner is ready for a final QC inspection – a quick check for any loose threads, cleaning and then packing.

What Shoe Factory Equipment do I need to make custom Sneakers?

Shoe Factory Equipment : How to make custom shoes?

Shoe Factory Equipment : What do I need to make custom Sneakers?

mini Shoe Factory equipment how to start a small shoe factory

There is a small but growing group of young shoe makers that are making high end custom shoes.  These shoe makers started repairing and replicating  Nike™ classic kicks but some have moved onto the creation of unique custom one-off shoes.
Wired™ magazine  recently ran a story on custom shoe maker Jacob Ferrato.   The article “Go Inside the Workshop of the Custom-Sneaker King” appears in the June 2016 Issue.   Read it Here!
See the Video here: JB Customs: Interview with Jacob Ferrato.

What equipment do you need to make a mini shoe factory?

What we are interested in is what shoe making equipment do you need to run a mini custom sneaker factory.  You can see in the article and videos a few different machines. These are real industrial machines you will find in any sample room of a large shoe factory.  These shoe sewing machines may be a little hard to find but they are all available in the USA, Europe and Asia.  If you want to start a small shoe factory these are the machines you will need.

Pattern Cutting in a mini shoe factory:

Cutting a custom shoe pattern For the custom shoe making process you can hand cut every piece with scissors or a sharp blade. Most shoe factories don’t actually buy cutting blades, they sharpen a small piece of steel in a few different shapes to suit what they are cutting.  In the video you can see a paper pattern template is used to trace the design onto the shoe materials.  The materials are then cut by hand. This process is used on all the leather and mesh parts.

Factory sample rooms have been looking at ways to speed up this process.  A large shoe factory will use a computer driven plotter cutter, water jet cutter, or even lasers to cut materials.  For a hand made shoe made without the use of a computer generated pattern, a machine like the new $2,300.00USD Glowforge machine may be the answer.  This laser will cut any design you draw on the materials.  This has the potential to revolutionize the custom shoe market. Check it out!

Custom shoe factory equipment Once the parts are cut you can see the edges are being skived.  In the video this is done by hand.  This is a time consuming process and it’s very easy to damage the cut shoe parts.  A shoe factory sample room will have a small electric skiver like this one, they don’t cost very much and will save time in our mini shoe factory.

Sewing Machines for a custom shoe factory

Flat bed sewing machines for a custom shoe factory In the Wired™ article you can see some of these the machines lined up.  The flat bed machine is the standard most recognizable type of machine. The machine is built into a table and run by an electric motor and has a foot control to advance the stitches automatically or one stitch at a time.  This is the most common machine for assembling the flat pattern parts of the shoe.

Once the upPost sewing machine per of the shoe has been stitched together, it needs to be “closed”. This closing operation creates an upper that cannot fit under the standard flat bed machine.  The second most common sewing machine you will see in a shoe factory is the “Post” style. Bulky items can fit under the machine for easy assembly.  This type of post sewing machine will be used to attach the tongue to the shoe or to secure the lining inside the shoe once it has been assembled into the final 3D shape.

small Custom Shoe Factory With the upper almost complete we will need a special sewing machine to finish it.  This machine is used to sew the bottom fabric onto the upper. This closes the upper. Now the upper is ready for lasting and assembly.

Now it’s time to assemble the sole onto the custom shoe.  There are two more pieces of shoe making equipment our mini footwear factory will need.  A sole press and a channel stitching machine.
sole press for a small shoe factory

Assembly of Custom Shoes

After the glue is applied to the upper and sole of the shoe it’s best to use a small press to make sure the bond is very strong.  A bench top shop press is not expensive and can generate enough force to press the parts together.

The final must have piece of equipment for a small custom shoe factory may be the most expensive.  This is a heavy duty channel stitching machine used to secure the upper to the shoe sole.  This machine to attach the shoe bottom to the uppersmachine is very powerful and can easily drive the needle and thread through the leather and rubber.

Because sole bonding with shoe cement is difficult for a mini factory, this machine insures the shoe bottom does not separate from the upper.   This machine has a long arm that can reach inside the shoe allowing the stitches to secure the rubber and upper together.

Local Market Shoe Materials

Picking Shoe Materials from Local Markets

Shoe materials In the major shoe making centers in China you will find thriving local markets for shoe materials. The local markets are store fronts large and small with every type of shoe material, shoe component and manufacturing equipment available.  You will find many store fronts displaying the material swatches available to order from a nearby factory or you will find shoe materials in stock that you can purchase immediately for use making samples. These market areas are very well organized, you will find streets lined with shoe material suppliers and even shopping malls crammed with all types of shoe materials.

I’m going to describe a busy shoe material market area in the town of Houjie. Houjie is located about 2 hours drive from the Hong Kong airport.  Houjie is an industrial city which is common to find in China. The city has a robust footwear and furniture industry.  Located within a 5 minutes walk from the Sheraton™ Hotel you will find hundreds of shoe material and equipment dealers.

What you will find in the shoe material markets?

Almost everything!  Except you won’t find many dealers that speak english and you may need help with translations. Make sure to take some business cards or catalogs so the dealer can see what kind of shoes you’re making. Also you should have your Pantone book to  check colors and bring a drawing of your shoes, this can help the dealer understand your needs.
The local material market is a great place to look for new ideas. The material market is also a good place to find materials for your sample shoes or a small production run. If you have a large production run, the material supplier will be happy help place an order directly with the factory.  You must be careful when purchasing shoe materials from the local market. The supply factory information may not always be available and there may not be material test reports. Therefore, before you use any local shoe material in your production, you need to get some lab tests done to make sure the material is suitable for your shoes.

Shoe Material Market LeatherThe material market in Houjie is a great place to find shoe leather. There are many different suppliers with all different types of leather. You will find leather in every color of the rainbow, from thick to thin, and in many different finishes.  You can buy leather by the hide or a dozen hides at once.  Of course, if you have a production order they can help you with that too.

Textiles for shoes are also plentiful in the local market.  You can buy swatch cuttings or 100 meter rolls.  You will find mesh for shoe uppers, shoe lining materials, and entire stores with reinforcing fabrics and strobal bottoms for shoes.

Shoe outsoles are also available in the local market.  You will find dealers with hundreds of outsole models on display.  These are “open” mold outsole units.  You can find flat treads, platform heels for women’s shoes, work boot bottoms, soccer cleats, casualShoe_Material_Market_shoe-outsoles bottoms and running shoe bottoms.   In the local market you will find “copy” bottoms of the latest shoe designs (without logos).  You cannot buy a single outsole 1 but you can order small runs of 5 to 10 units to make samples, then of course more for production.   The only issue with the local market outsole is the last bottom is already set. This may or may not work for your market.  You can buy the last with the outsoles or you can have a local last maker help you model the last to fit the outsoles.
Can you find shoe laces?  Yes, by the thousand!
Can you find metal hardware?  Yes!

How Shoe Outsole Tooling is Made

How to make shoe outsole tooling

How Shoe Outsole Tooling is Made


If you want to learn how shoe outsole tooling is made you are in the right place! All new outsole tooling starts with a designer’s drawing.  The designer should have followed the last bottom outline to get the shape close to the final design.  The shoe factory outsole technician will create a 2-D drawing for the designer to review.  The shoe factory’s technician has a lasted upper so that he can draw a top net that fits the shoe correctly.   Once the 2-D drawings are confirmed by the designer,  mold factory will make a 3-D CAD drawing that will be used to cut a prototype part.
Before any metal is cut, high density REN foam is cut so the designer and shoe factory can check all the details.   The REN foam is soft when compared to metal and can be cut very quickly.  The REN cutting machine running at high speed can cut the top, sides, and bottom of a new outsole design in just a few hours.  Shoe tooling for midsoles and outsoles is made the same way.

The REN model may be painted and sent to the designer for study.  The REN model can also be joined with the lasted upper to get the idea of what the final completed shoe will look like.
After the REN is approved, the design is sent to the metal shop. Depending on design, the metal may be cast, burned by high voltage electric discharge, or CNC cut by a computer controlled milling machine.  The molds are made from steel and aluminum. The flat rubber mold will be made from steel and cut by a CNC machine.  A midsole mold with high sidewalls and undercuts will be made from cast aluminum.  If the mold is made by casting process a REN must be made of each size, left and right. CNC cut molds don’t require every size to be cut.

While most of the footwear mold is created by machine, hand work is still required to make sure everything fits correctly.  Outsole and midsole parts must fit together tightly for good bonding. After a test pressing the outsole molds are returned to the shop for some rework.  This mold shop will also repair an outsole mold that has been damaged or worn out during production.  While the mold factory may be a loud and dirty place to visit, if you want to see how Shoe Outsole Tooling is made it’s worth a visit!  You will see many types of molding equipment for shoe soles.

A Day in the Life of a Shoe Designer

A day in the life of a footwear designer

A Day in the Life of a Shoe Designer

the daily life of a shoe designerLucky for us there is no “normal” day for a shoe designer!  The daily life of a shoe designer may be different every day! For a footwear designer every day will present a new challenge, almost every day will be a new adventure!  I can think of 10 different “days in the life of a shoe designer” that you can expect as a professional shoe designer.

The daily routine of a shoe designer will greatly depend on the size of the firm you are working for or, if you are working for yourself as an independent designer.  In a huge firm like Nike™ or Adidas™ you may find yourself in a large design group with your tasks focused on a relatively narrow aspect of shoe design and you may not find yourself working outside the department.  If you work for a smaller company your responsibilities will be wider, you will surely be working with many other departments.   As an independent designer you will be asked to work on many different design related tasks.

Also, the daily tasks for a shoe designer will greatly depend on the time of year or where you are in the footwear Design/Development cycle.  In a busy shoe design office there will be shoes in process for several different product release dates.  You may be in the concept stage for Spring delivery, while you are checking test patterns for Holiday delivery or confirming final samples for Fall production.

The Normal Office Day in the life of a Shoe Designer

There are some days for a shoe designer when you will really be sitting at your desk sketching shoes.  With so many demands on the shoe designers time these days may seem few and far between.  I have had weeks when I was tasked to just draw, 40 hours of just drawing is actually very difficult.

The footwear designers time is usually very mixed.  A shoe designers job description will be a long list of footwear tasks to work with. In the morning you may spend time making concept drawings or meeting with the creative manager to show some new logo applications.  Fed-Ex™ or UPS™ may deliver some shoes.  You may spend some time with your brands’ product manager and developer unboxing and organizing the new samples.  In the afternoon your brand team may meet and review each shoe, checking the shoe against the spec sheet or comment correction sheets.

The shoe designer may be working on a new last with the developer,  the new shoe is reviewed, fit tested or compared to reference samples.  The designer may check the new last to see if corrections were made.

The shoe designer will have meetings with the designer manger to get schedule updates, or with athletes and customers.

Travel Days

I hope you will have some travel days as a designer!  I’ve been lucky, as a shoe designer I have been able to travel the world.  Again, depending on your company, you may be parked in your office or you may be a road warrior.   The shoe designer may travel to visit factories, large dealers, trade shows, foreign distributors, sales meetings and inspiration trips.  While Skype can keep you in contact with your associates, there is no substitute for meeting face to face to work on a problem or celebrate successes.  Will you be traveling First class?  I doubt it.  Will you be traveling business class?…maybe, if you are a senior designer or design manager for a larger firm.  Will you spend many hours crammed in a coach seat on the way to China?  I would say, “Yes!  You will!” Just keep looking forward to being on the ground and working with friends.

Shoe Factory Visits

Leather for Shoes day in the life of a shoe designerMost likely you will be in a foreign county (China? Italy?), staying in a hotel close to your office or the factory.  Expect to get started early the morning.  If you are traveling with co-workers it’s very important to get everyone organized and on the same schedule.  The traffic in the industrial areas of China can be horrific, it’s critical to get started early or your factory visiting day will be spent in traffic!

Visiting factories to work on your projects or see new processes is great fun.  Expect long hours, some bad food, air conditioning or not….  Be flexible.  If there is another factory close by take the time to visit.  If you are visiting a large factory with many foreign visitors you may go about your business like a normal work day.  When you are working with a small factory you may need to spend some time drinking tea with the owners, this is standard procedure.

Depending on the company you are working for you may be invited to dinner.  Large firms have policies that don’t allow factory dinners, while for small firms the factory dinner is nessessary to create a personal bond between the companies.  Watch out!  While most factories owners mean well and just want you to have a good time, others just  try to get you drunk.  If business is good you can expect the factory business dinner to be a party.

Sales Visits

As a shoe designer you may be asked travel with a sales rep and visit with accounts.  These trips allow the designer to visit the retailer and hear first hand what they think of the products and markets.  For major dealer you may be asked to design some shoes on the fly.  You may also be asked to present your product during the sales call which is definitely a worth while experience.  If you have international distributors you many be asked to visit their market.

Trending Travel Days

Trend travel does not happen often but if you work for a large firm it can happen.  You and your fellow designers may travel to another city or country just to absorb the styles and trends.

Testing Trips

Depending on the type of product you are working on you may accompany your sample shoes on testing trips.  If you are working on hiking shoes or snowboarding boots you can expect some cold days in the snow.  Other shoes are often fit tested by your company staff or wear tested by athletes.

Sales Meetings

Shoe designers are often called upon to present the new products to the sales force.  The designers may present to salesmen in your home country or be flown overseas to educate an international sales force.

Critiques and Line Closing Days

Several times during the year the shoe designer will have to prepare for the line closing meetings.  In these meetings the new shoes are presented to CEO’s, marketing managers and sales managers.  The designer must prepare drawings, organize samples and be ready to explain why a new shoe should be in the range.

Shoe Trade Show Days

Footwear designers are often asked to attend major trade shows.  At trade shows the designers will assist the salesmen with large accounts and often help present the product lines.  You will find the customer greatly appreciates meeting the designers and will be happy to share their insights.

Shoe Making Process

Shoe Manufacturing Process

shoe making process shoe making process steps

How are shoes made in factories? The manufacturing process for shoes is basically the same for all types of shoes. The sports shoe manufacturing process used to make a kids sneaker, Air Jordan™, or women’s high heel fashion shoe are very similar. Shoe factories around the world follow the basic steps to make a shoe.

The basic shoemaking steps are:
#1.  Cutting upper parts
#2.  Stitching shoe uppers
#3.  Lasting and assembly

In this article, we will look at each of these factory processes for shoes. Of course, the number of operations is not 3. The number of operations is more like 30,000 depending on how you are counting.

Cutting Shoe Parts
Shoe Parts being cut, sports shoe manufacturing process

The shoe production process starts with cutting the materials. Shoe parts are generally cut by steel dies in a hydraulic press.   The cutting dies for shoe parts look like simple cookie cutters but they are very sharp. Every shoe part requires it’s own cutting die. Every part for every size needs its own die. These shoe parts are called the shoe pattern. To support the production of high volume shoes in popular sizes, often many die sets are required. The cutting dies are placed on the leather or fabric materials by hand, then the press closes to make the cuts.

Cutting die for sport shoe productionAfter the parts are cut a worker will carefully organize and stack the shoe parts. The parts will then be moved on to be processed before stitching. The parts will be marked for alignment or have logos added by the embroidery or printing departments.

Once the parts are prepared, the shoe factory workers will organize the parts into kits for the stitching department.

Stitching Shoe Parts

How shoes are made Stitching department, shoe manufacturing process flow charOnce the shoe parts are processed and organized, the shoe factory stitching department takes over. In the stitching department, the operations are divided into simple steps. Each worker is given one task to complete. For example, one worker will sew the vamp parts to the mudguard then pass the shoe onto the next worker to attach the eyestay parts. With each operation assigned to one worker, the QC staff can quickly track any problems. The division of the operations also allows the worker to quickly master their operation.
Shoe sticking process how to make shoesIn the stitching department, the upper parts are assembled, the lining attached, and the foam for collars and tongues are inserted.

The upper is completely assembled with the reinforcing parts added and heat molded into shape. Toe caps and heel counters are formed and ready for the final assembly operations.

Shoe lasting and assembly Process

the shoe assembly Process With the stitching complete, the upper is ready to be bonded to the outsole. Before the outsole can be attached, the upper must be “lasted.” Lasting is the operation that gives the shoe its’ final shape. The plastic, metal, or wood foot form (the “last”) is inserted into the upper. The upper is pulled tight, this sets the shape.

With the upper tight to the last, the outsole unit can be permanently cemented to the upper. During this process, the shoe travels inside a heat tunnel to dry the glue before the final bonding process. The last steps are QC and packing.

The Shoe Assembly Line how to make shoes The Shoe Assembly Line Chapter 12

The process of making shoes is covered in great detail in the book How Shoes are Made.  Inside How Shoes are Made you will find chapters on the cold cement process, vulcanized shoemaking processes, stitching, and outsole fabrication.

Footwear Mold Making Factory Tour

Footwear Mold Making Factory Tour

Footwear Mold Making Factory Tour

shoe mold factory Almost every modern shoe design project will require some sort of molded component.  From hidden heel counters, to outsoles, to fancy chrome plated logos you will need make some molds.  While some shoe factories will have limited molding equipment, very few will have the capability to make the molds.  To make molds for your footwear projects you will need the help of a footwear mold making specialist.

Located in the town of Humen in the heart of the South China shoe making trade, Dongguan Shi Desheng Mold Co. LTD is a typical footwear mold making factory.  This factory is well suited to make the plastic injection and compression tooling you may need for your new shoe designs.  When you visit a footwear tooling factory you are looking to see a team of CAD designers. They should be busy at work designing the molds.  Often the factory technicians will suggest modifications to make your parts stronger or easier to mass produce.

You will also be looking to see CNC machines, EDM machines and milling machines.

Shoes parts Cutting Mold The CNC or Computer Numerical Controlled milling machine is the work horse in the footwear tooling business.  You should see CNC machines busy cutting steel molds or copper electrodes.  At Dongguan Shi Desheng Mold Company you will see 10 CNC machines cutting.  Why 10 machines?  When a shoe factory orders molds they will often need the size run opened quickly.

Why are the machines used to cut copper electrodes?  Tooling steel is very hard and it can be very time consuming to cut fine details. Also, some details are difficult to cut in the negative required for molding.  To make these fine details, a soft copper electrode is cut then used to EDM   (Electrical Discharge Machining). The copper electrode is charged with high voltage then slowly lowered onto the steel.  An electrical spark will arc from the copper to the steel, burning away a tiny piece of metal.  As the electrode moves, the spark will jump to the next highest spot burning away more metal.

Shoe Construction Techniques

Shoe Construction Techniques

Shoe Construction Techniques

Shoe Construction TechniquesThere are many shoe construction methods from which a shoe designer can choose. Depending on the function and style of your shoe design, you have many options for connecting the upper to the outsole unit. The classic Goodyear welt, the heavy-duty Norwegian welt, and the modern cold cemented Strobel construction, to name a few.
Whether you are designing running shoes, Alpine mountaineering boots, or posh office shoes, you will need an understanding of shoe construction methods. Here we will review these common forms of footwear construction including board-lasted construction, Strobel construction, Blake Construction (also called McKay Welt), Blake/Rapid Construction, Goodyear welt construction, Norwegian Storm Construction, Stitch down Construction, and Bologna Constructions.

Need to know Footwear Construction Terms:

Welt:  A welt is a strip of leather, rubber, or plastic that runs along the perimeter of a shoe outsole. The machinery used for this process was invented in 1869 by Charles Goodyear Jr., the son of Charles Goodyear.
Outsole: Can be made of rubber or leather.
Midsole: Can be made of leather, cork, or foam.

Common Shoe Construction Styles

Board lasted constructionBoard Lasted Construction:  A very common shoe construction technique that can be made by machine or by hand. The upper is pulled tight and bonded to a fiber board. The outsole unit is firmly cemented to the upper, securing the upper to the sole. Board lasting construction can be used on almost any style of shoe, being suitable for many upper material types and outsole styles.
Strobel shoe construction
Strobel Construction:  Used for most athletic shoes, Strobel requires the upper material to be sewn to a fabric bottom creating a “sock.” The upper and bottom are joined by a Strobel stitch, using a Strobel machine.
With the upper sock tightly lasted, the upper is cemented to the outsole completing the shoe.
Blake Construction method Blake Construction: Used to make flexible leather shoes, the Blake construction starts with a board-lasted upper. Glue the sole in place then with the last removed, sew the upper directly through the outsole unit. The outsole may be leather or rubber and have a groove molded into its surface to guide the Blake stitch. You will find Blake construction on weltless leather dress shoes, moccasins, and boat shoes. Blake construction is not waterproof.
Blake_Radpid_Shoe_construction
Blake/Rapid Construction: Similar to the standard Blake construction, but with a “rapid” perimeter stitch attaching the outsole. The outsole covers the Blake stitching. This allows for a thicker sole and is easier to resole. The extra layer can be rubber, making the shoe more durable.
Goodyear welt construction technique Goodyear Welt Construction: The Goodyear welt is often used to make waterproof soles, the stitch that attaches the sole to the shoe runs around the outside edge and does not make stitch holes in the upper. The upper is sewn to the welts that attach to the insole and the outsole. During assembly, the welts are attached first by a horizontal “Goodyear” stitch, named for the inventor of the stitching machine, Charles Goodyear Jr. (also the son of the famous rubber inventor, Charles Goodyear Sr.).  The Goodyear welt construction method is ideal for heavy-duty boots for hiking or service.
Norwegian Storm Welt Construction technique Norwegian Storm Welt Construction: Similar to the Goodyear welt construction method but the upper is turned outside and is sandwiched between the outer welt and the outsole. Used to make the heaviest waterproof boots, the Norwegian Storm Welt is difficult to make and is found almost exclusively in the workshops of Italian bootmakers.

In this case, an inner welt or rapid stitch line sewn through the midsole is paired with a second rapid stitch that attaches the outsole. The outsole is attached after the first welt, the bottom stitch is protected by the outsole.

Bologna Construction: Developed in Italy and used primarily for dress or fashion shoes, the Bologna construction creates a smooth, comfortable shoe. The shoe lining is joined into a sock fitting the last tightly. The leather upper is then attached to the sole via the Blake stitching method. The Bologna shoe construction method is ideal for making very clean looking and flexible shoes.

How New Balance Shoes are Made

How New Balance Makes Shoes

What is the Process of Making New Balance Classic Shoes?    Most New Balance shoes are made by Cold Cement Construction process.   The New Balance classic trainer styles have a Sheet Cut EVA midsole.  This Midsole is attached by the Cold cement process. Cold cement is the modern updated style of shoe construction.  Cold cement is the opposite of the classic high heat vulcanized shoe construction, as found in Vans and Converse shoes.
Cold Cement shoe construction allows the use of modern lightweight plastic, foam and mesh materials due to the low temperatures required for bonding the upper to the shoe sole.   Every modern high performance athletic shoe manufactured by New Balance for Running, Basketball etc… is made by this cold cement process.

 

What is the Process of Making New Balance ShoesCold Cement / Sheet CUT EVA Shoe Assembly Process:

New Balance Classic with a  sheet cut EVA Midsole the shoe upper must be prepared  by board lasting.  For this running shoe the outsole will not cover the edge upper so it must be tucked under.   This is called “board lasting”.  The lasting board is made of treated fabric or paper board.

The shoe upper is steamed to soften the materials and the last is inserted and pulled tight.  A lasting machine is used to pull the upper tight.  The Lasting machine pulls the upper tight, while securely bonding the upper to the lasting board.    The lasting board remain inside the shoe, you can see it under the footbed.

The shoe may have a plastic or fabric part installed on top of the tongue to protect the surface from damage and drift during the lasting operations.

Sheet but EVA sole – Cut and Buffed and ready

While the upper is being lasted the sole unit being prepared. In this case a the rubber sheet sole is combined with the EVA foam cushioning component cemented to the underside.  This is done in a separate process that’s called stock fitting.

 

The sheet cut EVA material is cut into a profile then machined to follow the outside bottom shape.  A shaped grinding stone buffs the edge profile.

Now that the upper is lasted tightly and the outside unit is compete, the two pieces come together. The rubber sole unit will receive a coating of primer and cement. The outsole will get it’s own special primer designed for EVA and rubber. The shoe upper is also prepared with its own special primer and cement.

After the contact cement and primer has been completely dried in the heating tunnels the two pieces are joined together by hand. The skilled worked aligns the upper and outsole together then places the shoe is a hydraulic press.

The shoe will have some pressing operations, usually all done with one machine. A vertical press, toe and heel press and Side presses. This insures there is full contact between the upper and outsole. Once the shoe is pressed together it’s often put in the cooling tunnel to set the glue.

After the cooling tunnel a shoe de-lasting machine is used to push the last out of the shoe without wrinkling the upper.

Now the sneaker is complete at this point you can insert the foot bed.  The footbed may be molded EVA with a fabric cover or flat sheet cut foam.  The flat die-cut footed is usually cemented inside the shoe, while  molded footbeds are most often removable.

The new sneaker is ready for a final QC inspection, a quick check for any loose threads, cleaning and packing.
