The Asics GEL-DS TRAINER 25 W are the ideal choice for all lovers of long distance running. Their cleverly designed middle and midsole with FLYTEFOAM™ technology ensure that the shoe adapts to your every move. The PROPULSION TRUSSTIC™ technology used in the soles mirrors the foot's ligaments and creates a powerful lever to propel your stride. The GEL™ technology in the back of the shoe helps to reduce the shock upon impact. A special panel on the inside of the shoe ensures perfect fit, while the improved sockliner mimics the natural shape of your foot for greater comfort. And finally, the full ground contact sole ensures a smooth transition from foot strike to toe-off. Comfortable, durable, lightweight, those are the main characteristics of the GEL-DS TRAINER™ 25 running shoes by Asics.
