The minimalist and ultra-flexible Topo Athletic ST-3 road shoe offers multiple levels of cushioning and guidance for reduced stress during repetitive impact from road running. Stack Height : 16mm. Heel-to-Toe Drop : 0mm. Blucher-style knit upper features mesh details and minimally-printed overlays for a snug and secure fit. Completely neutral zero-drop platform promotes the most natural running experience. Lightly padded tongue and collar. Traditional lace-up closure. Removable insole. Collapsible heel allows easy packing of the shoe for travel or workouts. Durable rubber outsole with strategically-placed rubber pods for enhanced traction. All Topo shoes fit snug through the midfoot and heel to allow space for the toes to spread and splay, reducing that sloppy or disconnected feeling often associated with wider-fitting footwear.
