The Topo Athletic Mountain Racer trail running shoe is durable and rugged in a signature lightweight construction and roomy toe box that promotes a comfortable and natural running experience. Stack Height (Heel / Forefoot) : 30mm / 25mm. Heel-to-Toe Drop : 3mm. Ultralight and minimal-seam upper construction provides all-day comfort without weighing you down. Medial and lateral drainage ports increase water release and quick-drying capabilities. Padded tongue and collar. Traditional lace-up closure. Ortholite anti-compression footbed with antimicrobial properties that fight against odor and inhibit bacterial growth. Low Drop midsole promotes natural loading and foot motion during the gait cycle. Roomy toe box allows the toes to spread and splay naturally for greater foot function and comfort. Vibram outsole delivers unbeatable grip, traction, and durability. 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.
