The sole is an MD sole, which represents a material for the sole, with characteristics such as light weight, good elasticity, and seismic resistance.
The MD bottom is also known as the PHYLON bottom, commonly known as the Flying Dragon, which can reduce the burden on the feet. The midsole used in general footwear is a mixture of EVA foam that is heated and compressed (belonging to EVA secondary high-pressure molding products). The hardness is controlled by the foaming temperature.
In the production of midsole for some international running shoes, tennis shoes, and basketball shoes, MD is the main material, and can also be used to produce outsole for casual shoes. The professional term for MD soles is to inject material into a mold through secondary foaming, and then heat it twice at high temperatures before firing to form a shoe midsole. Therefore, MD is also known as a foam midsole.
Although this material is relatively soft and has a good elastic effect, its shockproof effect is also particularly good; However, when exposed to high temperatures, such shoes with MD soles tend to shrink and wrinkle.
