With only 23mm stack height, this do-it-all performance shoe keeps you close to the ground while still managing to be a favorite among passionate runners. The ultra light InnerFlex™ midsole provides impressive lightweight flexibility, while a weight-balanced Zero Drop™ platform helps maintain low-impact form, even when fatigue sets in at the end of hard race or workout. And with a FootShape™ toe box that allows your toes to spread out naturally for more stability and speed, you get a strong toe off to propel you further and faster.
