The ASICS® GEL-Evolution® III running shoe provides excellent support for excessive over-pronators without compromising flexibility, comfort, and exceptional upper fit. Biomorphic Fit™ upper provides a superior fit and function. DuoMax® support system helps ensure that the shoe maintains proper support for the foot during the critical transition from heel strike to toe-off. Impact Guidance System® (I.G.S) uses linked componentry that enhances the foot's natural gait from heel strike to toe-off. Solyte™ midsole material is lighter than standard ASICS® EVA and SpEVA® combined with improved cushioning and durability. Space Trusstic® system: an advanced system that creates a pocket between the Trusstic® system device and the midsole, allowing for greater midsole deformation and more efficient foot function.
