Eva midsoles are the most common cushioning materials in modern sports shoes.

Eva is now the most widely used midsole material for shoes. Higher quality shoes will have around 40 percent vinyl acetate and 60 percent ethylene the lower the amount of vinyl acetate the more brittle and likely to crumble the midsole will be. Soft and flexible eva is technically a foam instead of a rubber as it is formed by expanding plastic and trapping pockets of gas air in various densities.
