Impact Guidance System (I.G.S.®): ASICS® design philosophy that employs linked componentry to enhance the foot's natural gait from heel strike to toe-off. Heel Clutching System™: Exoskeletal heel counter provides improved support and creates improved heel fitting environment. Guidance Line®: Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency. Propulsion Trusstic®: Mimics connective tissue in the foot by creating tension as foot enters propulsion stage. AHAR®: Acronym for ASICS® High Abrasion Rubber. Placed in critical areas of the outsole for exceptional durability. ComforDry™ Sockliner: Provides cushioning performance and anti-odor properties for a cooler, drier, healthier environment. P.H.F.® (Personalized Heel Fit): 2 layers of memory foam line the collar and mold to the athlete's heel, creating a personalized fit. Rearfoot and Forefoot GEL® Cushioning System: Attenuates shock during impact and toe-off phases, and allows movement in multiple planes as the foot transitions through the gait cycle. Solyte® Midsole Material: A lighter weight midsole compound than ASICS' standard EVA and SpEVA®. Also features enhanced cushioning and durability. SpEVA® Midsole Material: Improves bounce-back characteristics and decreases midsole breakdown. Trusstic System®: Reduces the weight of the sole unit while retaining the structural integrity of the shoe.
