EVA rubber is better than foam and rubber;
Commonly used materials for flip-flop soles are: PE, PVC, TPR, high-elastic EVA, rubber, EVA rubber;
TPR and rubber are industrial rubber and natural rubber. They are wear-resistant but heavy. There is little difference between the two. Flip-flops mainly rely on the herringbone belt to bear the force, and the herringbone belt is narrow and thin if the sole is heavy. , It is easy to draw marks or wear out the feet, so it is not too recommended.
EVA is divided into high-elastic EVA and EVA rubber and plastic. This is used more frequently in shoes. The biggest advantages of both are good light resilience, non-absorption, odor, and wear resistance, but the non-slip performance is not good. If it is high-elastic EVA If there is water in the sole, it is like being on the ice; the advantage of EVA rubber and plastic is that it optimizes the anti-skid, and the proper ratio can achieve more than twice the anti-skid coefficient of the national standard.
