Mammut Sertig III Low GTX Women's Trail Running Shoes Black-Dark Frost

Fast, light, and fully waterproof, the Mammut Sertig III Low GTX is a women's trail running shoe built for high-tempo adventures on technical terrain. Its GORE-TEX Extended Comfort lining keeps feet dry through rain, mud, and stream crossings, while the breathable synthetic mesh upper and high-rebound EVA midsole deliver a responsive, agile ride. A Mammut Swiss Design rubber outsole with a 7 mm drop and trail-running last provides confident grip and stability on everything from forest singletrack to alpine Nordic walking routes.

Advantages

The Sertig III Low GTX pairs a PFC-free DWR-treated upper with a fully waterproof GORE-TEX membrane, so you stay dry without compromising breathability. The high-rebound EVA midsole offers energetic cushioning, while the 25 mm heel stack and 18 mm forefoot stack balance protection and ground feel. At just 280 g per shoe (UK 5.5), it disappears on your feet, and the lace-up closure ensures a precise, secure fit. Recycled content in the construction adds a responsible touch for eco-conscious runners.

Recommendations

For a glove-like fit, choose your usual running shoe size. The Sertig III Low GTX runs true to size and accommodates medium-volume feet; pair with thin merino socks for warm-weather runs or midweight socks for cooler hikes. Reapply a PFC-free DWR spray after heavy use to maintain water repellency.
