The Topo Athletic Fli-Lyte 3 road shoe offers multiple levels of cushioning and guidance for reduced stress during repetitive impact from road running. Stack Height (Heel / Forefoot) : 23mm / 20mm. Heel-to-Toe Drop : 3mm. Lightweight, breathable engineered mesh upper provides a comfortable and secure second-skin fit. Padded tongue and collar. Traditional lace-up closure. Ortholite anti-compression footbed with antimicrobial properties that fight against odor and inhibit bacterial growth. Roomy toe box allows the toes to spread and splay naturally for greater foot function and comfort. Low Drop midsole promotes natural loading and foot motion during the gait cycle. Rubber outsole offers durable 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.
