Air Mesh Upper - Allows air to permeate the exterior, providing breathability. Mizuno Wave - Provides cushioning by dispersing impact forces across a larger surface area. Stability is afforded by differing constructions of the lateral and medial sections of the outsole, whereby midsole compression is resisted in high pressure areas, namely, the medial side. This dynamic method of managing overpronation is far less intrusive than traditional medial posts. X10 - Carbon rubber outsole compound offers enhanced durability. Weight - 175 g
