Here I will be breaking down Midsole Materials. EVA AKA Ethylene Vinyl Acetate. EVA is the least expensive midsole material & is commonly found in entry level shoes (Think Nike Benassi Swoosh Slides, those are EVA).The reason it's so inexpensive to make is because the Midsole is cut & shaped directly from flat sheets of EVA Foam. am assuming they mean Lunar Foam in the Full Length setup is a Midsole Material. Lunar Foam is very difficult to explain in a paragraph but I will try my best. Lunar foam is a Hybrid of EVA & Nitril Rubber in a Nike Patented mix & process. It is 30% lighter then regular compression molded EVA & Phylon.
