Goodyear welted stitching
Footwear made using the Goodyear Welted (GYW) system, also known as the welted system, is synonymous with the most luxurious products in the shoe industry. It’s worth understanding the details of its construction to grasp why this method of shoe manufacturing has survived in nearly unchanged form since the 15th century (the first references) and continues to find passionate enthusiasts today.
The Welted System (Goodyear Welted or GYW) of Shoemaking
Let’s start from the beginning, specifically with the name. This is because its main structural element is a welt. The term "Goodyear Welted" is relatively new, originating in the late 19th century, and is closely associated with the early stages of mechanizing shoe production. Why "Goodyear Welted"? That’s a topic for another story. Why is the name so important? Well, the shoemaking craft in Poland has its own specificity, particularly in terminology. It turns out that in different regions of the country, the same elements of shoes have drastically different names. This is because old master shoemakers often learned from Germans, Russians, Hungarians, Czechs, and others.
The welted system (in shoemaking, a "system" refers to the method of assembling the shoe) is one of the oldest known assembly systems, as mentioned earlier. Its excellence is proven by the fact that it has survived in nearly unchanged form to the present day and is still widely used. Of course, over the centuries—especially in the 19th and 20th centuries—many variations and modifications have emerged, but in this article, we’ll focus solely on the classic version. Simply put, the classic welted system involves stitching the lasted (shaped and stretched over the last) upper to the insole and welt with a horizontal seam, and then sewing the outsole to the welt with a vertical stitch.
The Goodyear Welted System (Welted System)
Here, we should clarify a few terms, such as:
Upper – The outermost layer of the shoe, typically leather.
Lip – A part of the insole that is either cut from its thickness or attached to it, allowing the welt to be sewn onto it.
Insole – The component inside the shoe that has direct or indirect (via the lining) contact with the foot.
Filler – Usually cork, which smooths out the unevenness caused by overlapping materials and also provides cushioning and thermal insulation.
Channel – A diagonal cut in the outsole at the stitching point. Since the seam joining the soles is hidden within the outsole, it is protected from premature wear.
Advantages and Benefits of the Goodyear Welted System
As you can see, welted footwear has a complex construction, making it labor-intensive and expensive to produce. It also requires the use of high-quality materials, as only these can meet the demands of the various structural elements.
For this reason, welted shoes are primarily made as luxury footwear. Despite the development of new technologies, this construction method has proven indispensable in the production of specialized footwear, such as military boots. Its exceptional durability and relatively high flexibility contribute directly to the shoe’s longevity and comfort. This is achieved through the horizontal welt seam, which does not stiffen the shoe, as well as the use of premium materials. The key components of the shoe's durability are the insole, specifically its lip, and, of course, the welt.
The use of high-quality materials has another significant advantage: they allow the foot to breathe freely by creating an optimal microclimate inside the shoe. This is why the welted system is ideally suited for luxury footwear. Such shoes are often chosen in situations where one needs to look great while working 8 or more hours a day.
