The Topo Athletic Phantom 4 is a high-cushion road shoe with a 5mm drop and a roomy toe box for natural toe splay. The ZipFoam midsole delivers a soft, responsive ride for long easy miles, while a refreshed engineered mesh upper improves midfoot lockdown without sacrificing breathability. A rubber outsole with strategically placed lugs adds durability and grip on the road, day after day.
