Materials: The single layer of engineered mesh is ultralight, reactive and highly breathable. No-sew support in the forefoot and metatarsal areas aid feet as they tire at the end of the race.The nonlinear lacing setup locks feet in place and a new traction pattern offers superior grip even in wet conditions.
