Exploring Shoe-Making Techniques: A Comparison of Sock Lasting and Stuck On Processes

When it comes to making shoes, there are a variety of techniques used to attach the upper to the sole. Two of the most common techniques are sock lasting, also known as stroble lasting, and stuck on process. In this blog, we will explore these two techniques in detail and compare their advantages and disadvantages.

Sock Lasting (Stroble) Process

The sock lasting, or stroble lasting, process involves stitching the upper directly to a sock liner (stroble/ Non woven cloth), which is then wrapped around a last. The upper is stretched over the last and the edges of the sock liner are pulled up and secured around the edge of the last. The sole is then attached to the sock liner using an adhesive or cement.

One of the advantages of the sock lasting process is that it allows for greater flexibility in the shoe, as there is no rigid insole. This can make the shoe more comfortable and better suited for activities that require more movement, such as running or hiking. Additionally, the sock lasting process is more efficient than traditional shoe-making techniques, as it eliminates the need for a separate insole and lasting process.

However, one of the drawbacks of the sock lasting process is that it can result in a less durable shoe. Since there is no insole, the sole is attached directly to the upper, which can cause the shoe to wear out more quickly. Additionally, the sock liner can stretch and deform over time, which can affect the fit of the shoe.

Stuck On Process

The stuck on process, also known as the cemented construction method, involves attaching the upper to the sole using an adhesive or cement. The upper is first lasted to a Insole board (texon Board), which is then attached to the sole using the adhesive. The shoe is then allowed to dry before any excess glue is trimmed away.

One of the advantages of the stuck on process is that it results in a more durable shoe. The midsole provides an additional layer of cushioning and protection, which can help to extend the life of the shoe. Additionally, the stuck on process allows for greater precision and control during the shoe-making process, as each component can be attached separately.

However, one of the drawbacks of the stuck on process is that it can result in a stiffer shoe, as the midsole can limit the shoe’s flexibility. Additionally, the stuck on process is less efficient than the sock lasting process, as it requires multiple steps and components.

In conclusion, both the sock lasting and stuck on processes have their advantages and disadvantages when it comes to shoe-making. While the sock lasting process can result in a more flexible shoe and is more efficient, the stuck on process can result in a more durable shoe and offers greater precision during the shoe-making process. Ultimately, the choice between these two techniques will depend on the specific needs of the shoe and the preferences of the shoe-maker.
