The GEL-DS TRAINER? 26 running shoe is the recommended choice for runners covering shorter distances who want to go fast. The shoe helps you achieve those running goals with an improved upper fit that moves seamlessly with the runner's natural motion. Updated with a soft and flexible knit upper this application helps the shoe move more naturally with the runner's foot. Accented with a series of reflective details this design element is practical for runners who are training in low-light conditions. Added support stems from the updated sockliner which naturally contours to the foot's shape while improving comfort. Following a more sustainable design approach this shoe also uses fewer resources to color the sockliner. Functional for overpronators the shoe's DUOMAX? technology on the midsole's medial side helps reduce the foot's pronounced inward roll and improves support. GEL? technology cushioning improves shock absorption while the FLYTEFOAM? midsole material provides a soft and supportive feel from footstrike to toe-off. The PROPULSION TRSTIC? technology in the outsole mirrors the foot's ligaments creating a powerful lever to propel your stride. Formulating a smoother transition throughout your stride this shoe is also complemented with an AHARPL? heel plug to improve durability and expand its lifespan.
