The Topo Athletic Phantom road shoe offers multiple levels of cushioning and guidance for reduced stress during repetitive impact from road running. Stack Height (Heel / Forefoot): 30mm / 25mm. Heel-to-Toe Drop: 5mm. Breathable, lightweight engineered mesh upper with lightly-printed overlays and an external TPU heel counter for a secure fit and all-day comfort. Padded tongue and collar. Traditional lace-up closure. ZIP FOAM midsole compound is springier than EVA and provides more rebound over the life of the shoe. Roomy toe box allows the toes to spread and splay naturally for greater foot function and comfort. Strategically placed rubber outsole provides enhanced 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. Imported. WARNING Measurements: Weight: 9 oz Product measurements were taken using size 8, width B - Medium. Please note that measurements may vary by size. Weight of footwear is based on a single item, not a pair.
