The PGuard Toe protector design enhances durability and helps protect your toes as you make quick directional changes. Solyte Midsole material is a lighter weight midsole compound than ASICS' standard EVA and SpEva. Two layers of memory foam line the collar and mold to your heel to provide increased protection throughout long matches. The outsole of this shoe is one of the best around. The Trusstic System reduces the weight of the sole unit while maintaining it's structural integrity and the ASICS High Abrasion Rubber is placed in critical areas on the outsole for durability.
