The GEL-DS TRAINER™ 25 running shoe from ASICS is an excellent choice for runners who want to go fast. The shoe helps you achieve those running goals with a great fit around the midfoot and lightweight FLYTEFOAM® technology in the midsole for a snappy response. This limited model offering also celebrates the city of Boston and the city's annual marathon with a special colorway. The PROPULSION TRUSSTIC™ SYSTEM technology in the shoe's outsole mirrors the foot's ligaments, creating a powerful lever to propel your stride. GEL® technology in the rearfoot also adds cushioning to reduce the severity of shock upon impact. A specialized panel on the inside of the shoe helps provides a great overall fit, while the new contoured sockliner mirrors the natural shape of the foot to promote greater comfort. Additionally, the full ground contact design of the outsole formulates a smooth transition from foot strike to toe off.
