Background

The rubber sole is a sole made of rubber, and the rubber sole material can be roughly divided into natural rubber or artificial synthetic rubber, and the natural rubber has the advantages of being very soft, excellent in elasticity, suitable for various exercises and playing a role in shock absorption, but also has obvious disadvantages of being poor in oil resistance, ozone aging resistance and thermo-oxidative aging resistance;

EVA sole refers to the sole that uses EVA material to make. The EVA sole has high rebound resilience and tensile resistance, high toughness, good shockproof and buffering performances, excellent heat preservation, cold prevention and low temperature performance, capability of resisting severe cold, closed cells, good sound insulation effect, closed cell structure, no water absorption, moisture resistance, good water resistance, seawater, grease, acid, alkali resistance and other chemicals corrosion resistance, and is antibacterial, nontoxic, tasteless and pollution-free;

the prior (application number: CN200820128039.1, an EVA rubber composite sole) adopts EVA and rubber to combine and make the sole, and combines performances, but has the structure that: the rubber material is directly exposed by compounding a rubber layer on the front sole and the heel of the sole of the EVA base layer, and the defects of poor oil resistance, ozone aging resistance and thermo-oxidative aging resistance still exist.
