The lightweight running shoe that will do it all, no matter the terrain the Fast Trac NITRO. It’s capable on any surface, including loose trails and gravel, thanks to the dual foam midsole combining full length NITROFOAM and a layer of ProFoamLite and the durable PUMAGRIP ATR outsole. Integrated eyestays allow for a snug fit, and details at the toe provide both drainage and protection from debris.
