Topo - Connect is for minimal shoe enthusiasts looking for an all-terrain shoe for running, walking and daily wear. Topo - Connect is the most minimal shoe, allowing for optimal ground feel. With no midsole and an all-terrain Vibram XS Trek outsole, the total stack height of Topo - Connect is 10.5 mm, for a flexible and natural ride. For an even more minimal ground feel, Topo - Connect offers a removable insole and a finished footbed, reducing the stack height to just 5.5 mm-composed solely of rubber and strobel board when the insole is removed.
