As Topo Athletic's most cushioned road running shoe to date, the Phantom features their signature roomy toe box with a thick layer of Zipfoam for unmatched impact protection. A new proprietary midsole, Zipfoam provides lightweight cushioning that has more rebound than traditional EVA so you can extend your mileage with less impact on your joints.
Meanwhile, the engineered mesh upper secures the foot in place with breathable comfort, and strategically placed rubber provides grip and durability where needed. Those that like maximum cushioning but still want natural toe-splay will love Topo Athletic's Phantom.
