Close the gap between your weekend training run and race day in a durable design that can be worn not only at the start line of your favourite race, but in the days and months following your victory. It offers comfort and reliability, but with a propulsive feel for a fast, fresh feel. This kind of versatility is unusual in the running arena. But who said you can't have it all? More cushioning The newly developed Nike ZoomX foam is responsive and lightweight. The foam is curved in shape and ensures support during all three phases of the stride cycle. It provides flexibility as the foot disengages from the ground, a smooth running feel as the foot moves forward, and cushioning during ground contact. Cooling comfort Lightweight mesh in the upper provides a softer, more breathable feel and conforms to your foot. Supportive fit The mesh is interwoven with the laces for a secure midfoot feel. The shoes tighten when you lace them up. In addition, the forefoot and heel have a slightly wider base for more stability.
