With the brand new ASICS Gel-Resolution 7, tennis players will appreciate that this update maintains the optimum stability and cushion of its predecessors. The Flexion Fit® upper provides players with the comfortable support and protection around the toe and midfoot. This update features a slightly different design to the upper for a polished look. The High Abrasion Rubber material on the outsole continues to ensure durability and traction after many hours on the tennis court. Upper: Flexion Fit® proprietary upper provides form-fitting comfort without sacrificing support. Padded tongue and P.H.F™ heel collar enhance comfort. Lace-up front offers an adjustable fit.Midsole: Rearfoot and forefoot GEL® cushioning systems attenuate shock during impact. Solyte® midsole material is a lighter weight midsole compound than ASICS' standard EVA or SpEVA®. Midfoot Trusstic System reduces the weight of the sole unit while retaining the structural integrity of the shoe. Impact Guidance System (I.G.S®) design philosophy employs linked componentry to enhance the foot's natural gait. OrthoLite sockliner provides additional cushioning and an anti-bacterial treatment to reduce odor. Outsole: Non-marking outsole. AHAR® (ASICS High Abrasion Rubber) is placed in critical areas of the outsole for exceptional durability.
