Provides a high-tech solution for runners who demand extreme shock attenuation. Designed to accommodate gaits ranging from mild underpronators to moderate overpronators. FluidFit™ upper combines multidirectional stretch mesh with stretch reinforcements that adapt to your foot, creating a truly customized glove-like fit. Discrete Eyelets are independently placed to disperse lace tension, creating a customized fit environment for enhanced upper comfort. Heel Clutching System™ improves support and creates a better heel fitting environment. Solyte® cushioning in the midsole is lightweight with enhanced cushioning and exceptional durability. Heel and forefoot GEL® Cushioning Systems and Impact Guidance System (I.G.S®) absorb and disperse shock during impact and toe-off phases, allowing natural foot movement as you move through the gait cycle. Discrete Heel Unit takes I.G.S. to a new level by creating a high degree of shock attenuation and stability. Guidance Line® technology employs vertical flex grooves to decouple the tooling along the line of progression for enhanced gait efficiency and performance. High Abrasion Rubber (AHAR) is placed in critical areas of the outsole for durability. DuraSponge for enhanced cushioning and durability in the forefoot. International Shipping is not available.
