EVA stands for Ethylene-vinyl acetate, which is a polymer that
has excellent stress and impact resistance properties. The midsole
of a shoe can be a misleading term: it does not refer to a position
in the middle of the shoe, but is the material between the outsole
and upper. It's common to find an EVA midsole in sneakers which
come under a great deal of stress. Basketball is one such sport,
which requires extra cushioning and impact resistance for it's footwear.
The above Nike Dunk High is one such sneaker which features a EVA
midsole. Running and skateboarding footwear are two other sports
which often require a EVA midsole to provide a comfortable shoe.
