The same low-profile youve come to enjoy sees an update with lateral Propulsion TrussticA(R) technology that allows for more response and control during intense play. New colors will bring your whole look together. Upper: PGuardA(R) Toe Protector is designed to enhance durability. P.H.F.(TM) (Personal Heel Fit) provides 2 layers of memory foam to line the collar and mold to the heel, creating a personalized fit. Flexion FitA(R) upper provides form-fitting comfort without sacrificing support. Lace-up front offers an adjustable fit. Midsole: Rearfoot and Forefoot GELA(R) Cushioning Systems attenuate shock during impact and toe-off phases, and allows movement in multiple planes as the foot transitions through the gait cycle. SolyteA(R) Midsole Material is a lighter weight midsole compound than ASICS standard EVA and SpEVAA(R) and features enhanced cushioning and durability. Lateral Propulsion TrussticA(R) mimics connective tissue in the foot by creating tension as the foot enters propulsion stage. Outsole: AHARA(R) High Abrasion Rubber placed in key areas of the outsole provides exceptional durability.
