What is the role of the double sole of the labor shoes?

In the combination of the current shoe sole material, the double sole has become the most convenient and best solution. The protection of the sole is achieved by the wear resistance and anti-slip performance of the outsole, which is realized by the light and soft characteristics of the midsole. Comfort when walking.

From this point of view, the current best combination is RU / PU, using rubber (RU) to make the outsole, polyurethane (PU) as the midsole, and then through the adhesive or chemical bonding function and the bonding function of PU itself bonds the outsole to the midsole. Of course, the outer sole of the shoe can also be polished, burnished, and carved.

There is also a combination of sole material, namely PU/TPU (polyurethane/thermoplastic polyurethane). It is comfortable to wear. Moreover, the use of thermoplastic polyurethane to make the outsole meets the needs of contemporary designers, because the sole made of TPU can produce a colorful sole, and the carving process on the sole can also be varied.

Another double-layer sole made of PU/PU (polyurethane/polyurethane) material combination, the outsole and the midsole are made of polyurethane. For the outsole, a particularly dense polyurethane material must be used to maintain the wear resistance characteristics of the outsole. For the midsole, foamed polyurethane must be selected for comfort.
