Designed for runners seeking a daily trainer that provides additional support as well as incredible cushioning. An EVA film sits sandwiched between two layers of Fresh Foam X to provide underfoot stability from heel to toe. An all-new rockered profile with two additional mms of stack and vertical outsole flexgrooves offer smoother transitions than ever before experienced in the 860 franchise. The Double Jacquard engineered mesh offers a premium fit and finish, adding additional security on the medial side thanks to extra structured zonal supports.
