The process of making shoes is more complex than you might think. Many people believe the material of the shoe is what’s most important, but the construction of the shoe is just as vital. Just as there are different kinds of shoes, there are also various types of construction methods. Learning how shoes are constructed can help people choose boots and shoes with ease. We put together a guide regarding the different types of boot construction methods, so read on to learn more.

Cemented Construction

Cemented construction is just one of the different types of boot construction methods. We should note that ALTAI® uses the cemented construction method. With the cemented construction method, the upper part of the shoe is glued to the sole with a strong adhesive. This method is different from others because there’s no stitching or welt involved. This is more of a disposable shoe as it falls apart more easily than other construction methods. Typically, fast fashion companies use this construction method. One way to tell if a shoe is constructed this way is to look at the outsole, since a cemented shoe doesn’t have stitching. The outsole is the material that’s at the bottom of the shoe’s exterior. This is the part of the shoe that touches the ground.

Vulcanized

Another construction method for shoe making is referred to as vulcanization. The vulcanized method is mostly used to make sneakers, but rubber boots can also be made this way. This method is more durable than cemented construction. The process of vulcanization makes the rubber more durable. An interesting process is used to make shoes this way. Chemicals and high heat are used to melt the rubber, which allows it to bond with other materials. This is an efficient method because multiple shoes can vulcanize at the same time. This means it’s cheaper to produce shoes this way. Since these shoes are made in a chamber, you might be wondering how they’re made. An aluminum last is used to ensure it can endure the extreme heat in the chamber.

Blake Stitched

The Blake stitch is another construction method for shoes. Lyman Reed Blake originally thought of this method, but eventually sold the patent to Gordon McKay. Some people refer to it as Blake Stitched, whereas other refer to it as McKay. Either name is recognized. This is one of the first mechanized methods for making shoes. It’s a quick and simple method, which makes it cost-effective.  A Blake stitched shoe has a stitch that goes through the insole, outsole, and upper. As previously mentioned, the outsole is the part of the shoe that touches the ground. The insole is the inside of the shoe, and the upper is the part of the shoe that covers the foot. Most shoes made using this construction method are not water-resistant. Blake stitched shoes can be resoled if the machine can do Blake stiches. The number of times a shoe can be resoled is limited since new holes are created in the uppers to remake the stich.

Goodyear Welt

The Goodyear welt is the most well-known type of shoe construction. The patent for this construction method was passed around from one person to another, but it ended up with Charles Goodyear Jr. This is where the name comes from, as you might have guessed. One of the biggest differences from other methods is that there’s a canvas rib under the insole. The canvas rib is glued to the perimeter of the sole and a leather strip is attached. A welt is a strip of material that’s sewn around the edge of an upper. It’s common for the welt to be leather, but it can also be made of a different material. The Goodyear welt method makes durable and water-resistant boots. Another benefit associated with this construction method is that it’s easy to resole. This is because you can remove the sole stich and outside without the upper and insole being affected. The only downside is that shoes made with this construction method are not as flexible as a Blake stitch, for example. This is one of the only downsides as this construction method is very water-resistant and durable.

Hand Welted

Another method for shoe construction is hand welting. This method is essentially the same technique as Goodyear. The difference is in the name, as this construction method is not done by machine. After the shoe last is complete, the welting is done by hand. This construction method is not as common as some of the other construction methods. Very few shoemakers use this method as it’s very time consuming. The amount of time it takes to hand welt a shoe makes it very expensive.

Norwegian Welt

Lastly, the Norwegian welt is another construction method used to create boots. This method originates in Italy. This construction method is intended to make shoes that are waterproof. Rather than attaching the upper to the feather of the insole, it does something different. The upper is turned outward and runs parallel with the outsole. The Goodyear has only one exterior stitch, but the Norwegian has two. The outsole stitch holds together the upper, midsole, and outsole. The Norwegian stitch keeps together the upper and the insole. A cavity is created between the welt and the insole. A filler is often used to cover this cavity. Cork is commonly used to fill this cavity, but other materials can be utilized as well. Norwegian-welted boots are the most reliable construction method.

When you buy boots, it’s important to understand the construction methods used to make them. This ensures that you buy the right boots for your lifestyle. The construction method is just as important as the materials used, so make sure to do your research.
