The 25th edition of the Asics GEL-DS Trainer builds on the success of the last version by continuing the fantastic fit of the knit upper. This version also sees a new contoured sock liner for better connection between you and the shoe. FLYTE FOAM keeps things light. The newest version of the GEL-DS Trainer is softer, but still supportive. This is, after all, a lightweight stability shoe for those who need some additional support when they are going faster. Propulsion TRUSSTIC technology combined with a full contact outsole contributes to a smooth transition from foot strike to toe off.
