The TeraNova foam roller is constructed with the same material used for decades for cushioning in running shoes. This foam is a dense, cross-linked foam which means the foam can withstand a lot of deflection and rebound without breaking down. EVA foam has excellent memory characteristics meaning it will regain it"s original shape after being compressed. Rounded corners on the roller add to the comfort level. Foam rollers are also used for self massage of the quads, hamstrings, calves, upper and lower back and are popular with runners for IT band massage.
