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 Nitro foam 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.
