Its circular-knit upper stretches in key areas, while the dynamic heel design and molded tri-star outsole pattern work together for an adaptive ride that connects you to your run. Circular-knit upper provides strategic stretch and support. Dynamic Flywire cables deliver a locked-down fit. Tri-star outsole pattern enhances flexibility. Minimal heel design is made with soft foam to secure the back of your foot while allowing natural movement. Co-molded midsole uses a softer injected unit (IU) core foam directly underfoot and a slightly firmer injected unit (IU) carrier foam to deliver softness and support just where you need it.
