The ASICS® GT-2130™ running shoe continues the 2000 series tradition by delivering all the great comfort and fit features that runners expect. Impact Guidance System (I.G.S.®) linked componentry enhances the foot's natural gait from heel strike to toe off. Solyte™ midsole offers improved cushioning and durability. Space Trusstic System® creates a pocket between the Trusstic System® device and the midsole, allowing for greater midsole deformation and more efficient foot 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. Wt. 11.9 oz.
