Asics Gel-Kayano 21 Men's Structured Running Shoes, Black/Silver

The latest edition of Asics' Gel-Kayano 21 updates the classic running trainer with the most up-to-date versions of its trademark technology. FluidRide™ midsole technology provides the ultimate in bounce-back and cushioning while retaining its lightweight and durable properties, with GEL cushioning attenuating shock during impact and toe-off for a smooth, natural stride. Stitched around an EVA board and directly attached to the SpEVA® and Solyte® midsole, the upper provides a snug fit that prevents slipping and rubbing, while the ergonomic ComforDry™ sockliner can be removed to accommodate a medical orthotic. Designed for neutral- and overpronators, the Gel-Kayano 21 naturally adjusts to the needs of your feet, and provides maximum comfort for the duration of your run.
