Rear and Forefoot Gel - ASICS trademark cushioning system which absorbs impact force superbly, dampening shock in the initial heelstrike and allowing for a smooth transition through the step, greatly increasing comfort and performance and reducing the risk of injury. * Pivot Point Outsole - Encourages multi-directional movement through a circular pivot point on the outsole of the shoes which give you great traction and manoeuvrability for those sharp turns on the court. * Trusstic System - Under the arch is a plastic component which gives the shoe great strength and enhances flexibility and stability. * Compression molded EVA midsole - Helps to give a very cushioned ride to the runner and increases bounce back. * Non-Marking Outsole - Non Marking Outsole - Ideal for court sports, leaving you free to move sharply without marking the floor.
