In the sole products of the prior art, the sole materials generally comprise at least two systems, one is a physical "crystallization" system of plastics made from raw materials of SBS (styrene-based thermoplastic elastomer) and SEBS (linear triblock copolymer with polystyrene as the end segment and ethylene-butylene copolymer obtained by hydrogenation of polybutadiene as the middle elastic block); a chemical reaction method 'cross-linking' system using high-molecular material such as PU (polyurethane) and RB (rubber) as raw material features that both systems can be injection moulded by fusion injection technology.

Both systems, although widely used, have corresponding disadvantages:

the SBS and SEBS materials of the first system are high in price, and are easy to vulcanize at high temperature and poor in wear resistance;

in the second system, the forming and vulcanization of the rubber sole are carried out separately, although the material cost is relatively low, the process cost is high, in the vulcanization process, if pores exist inside, the vulcanization process is difficult to ensure that the whole semi-finished product is vulcanized uniformly, the dynamic balance effect of the finished product is poor, after vulcanization, high-pressure gas in the pores is easy to expand rapidly and explode when the mold is opened, so that the thin walls of the pores are broken to become waste products, and the rejection rate is high in the process; it should be noted that the vulcanization is carried out in a special vulcanizer, and the rubber product needs to be pressurized and heated again, which consumes energy, time and cost, and is a major disadvantage of the rubber product process.
