Foam and Cushioning Materials
Foam and cushioning play an important role in making shoes comfortable. They are often used in the soles and insoles to provide support and absorb shock as we walk or run.

One of the most common materials used for cushioning is EVA foam (Ethylene Vinyl Acetate). EVA foam is lightweight, flexible, and provides great cushioning. It is made by combining different chemicals, then heating and molding them into a soft, rubber-like material. This foam is often found in running shoes and athletic footwear, as it helps protect the feet from impact.
