The Norvan LD 3 GTX is engineered for lasting comfort and performance on longer trail runs. Designed to excel over unpredictable terrain, the abrasion-resistant Cordura mesh upper works with a GORE-TEX membrane, for lightweight, durable, breathable waterproof protection. In response to uneven ground, a stacked heel and forefoot aids shock absorption, and the toe box constructed to allow for splay and natural movement, allows for proprioceptive stability. The In Fuse midsole guards against foot fatigue, and a Vibram Mega Grip rubber outsole ensures sure-footed confidence and traction. Intended to keep you moving in all conditions, these shoes are challenge ready.
