The Asics’ GEL DS-Racer 7 running shoe was created to facilitate speed, being ideal for fast paced running over short distances. Asics’ lightest racing shoe (203grams), the DS Racer combines a Soylte midsole for substantial weight reductions and Duimax and Trusstic systems for support and stability – essential when running at speed. In conjunction with this, the GEL systems on both the rear and forefoot provide essential impact reduction to lessen the wear on the foot. This is an excellent sprinting shoe, for serious runners who are looking to maximize performance through an exceptionally light model.
