The Magic of the Midsole
The key to the Peg Turbo, as noted earlier, is the lightweight foam in the midsole. Lightweight foams are nothing new, of course. But typically, feathery EVA midsoles compress easily and are slow to recover adidas nmd womens cheep sale their shape. ZoomX, by comparison, is still highly compressible under your weight (giving you the soft landing), but it rebounds quickly to propel you forward.The foam is made from Pebax, which is more typically used for plastic bridges and other molded parts in shoes. For example, Mizuno has used it in a Wave plate. Pebax has a lower density than some thermoplastic alternatives (thus, it’s lighter), but is also flexible, resists impact, and returns energy. Those properties remain when it’s blown into a foam. Adidas Gazelle mens says this new foam weighs roughly one-third as much as Cushlon—the midsole material you’ll find in the ordinary Pegasus—yet delivers more cushioning than that shoe. It also delivers greater energy return—Nike reports ZoomX retu...
