MODEL Outsole Material Introduction

MODEL (MD) outsole is mostly used with rubber outsole. It is made from EVA material by two times foam. It's lighter and has better elasticity than EVA, It's wear-resistant and not easy to deformation, but the color is too dark, glossy, and has air holes. The process is complex, costly, and time-consuming. It has begun to be eliminated.

IP outsole is made of EVA material injected, it's 30% lighter than MD outsole (scientifically determined, the foot is one gram lighter, the burden of the spine burden is reduced by 6-10 grams). It's glossy, smooth, and has no air holes. The material is meticulous, flexible, wear-resistant, and lightweight. It is the best outsole material nowadays, but the price is high. Most outdoor running shoes use this sole material.
