Ideal for underpronators to moderate overpronators. Upper: Padded tongue and heel collar enhance comfort. Lace-up front offers an adjustable fit. Synthetic overlays provide lightweight support. Mesh provides breathable flexibility. Midsole: Guidance Trusstic SystemA(R) integrates Trusstic SystemA(R) and Guidance LineA(R) for enhanced gait efficiency while providing midfoot structural integrity. ComforDry(TM) Sockliner provides cushioning performance and antimicrobial properties for a cooler, drier, healthier environment. SpEVAA(R) Midsole material improves bounce-back characteristics and decreases midsole breakdown. Rearfoot and Forefoot GELA(R) Cushioning Systems attenuate shock during impact and toe-off phases, and allow movement on multiple planes as the foot transitions through the gait cycle. Maximum Support Last provides more depth and width throughout the mid- and forefoot to accommodate athletes with higher volume feet or who wear orthotics. Impact Guidance System (I.G.SA(R)) employs linked componentry to enhance the foots natural gait fro m heel strike to toe-off. Outsole: DuraSpongeA(R) outsole is a blown AHARA(R) rubber compound for enhanced cushioning and durability in the forefoot. Guidance LineA(R) vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.
