"What Our Gearhead® Experts Are Saying:""I reach for a non-waterproof hiker on warm weather days when breathability matters more than wet weather coverage, and the Sertig III Low nails that balance. The engineered mesh keeps air moving even on exposed climbs, and the high rebound midsole gives it a livelier feel than most shoes at this weight.""Summer mornings on dry singletrack call for a shoe that moves well, breathes freely, and stays out of the way, and the Mammut Sertig III Low was built for exactly that kind of day. Mammut designed this low-cut hiker around a breathable double layer engineered mesh upper that keeps airflow high when the sun is overhead and the trail is climbing, making it a natural fit for warm weather outings where staying cool matters as much as staying comfortable. The high rebound Critical EVA midsole brings a cushioned, responsive platform to every stride, absorbing the repetitive impact of long descents while giving something back on the flats. An Ortholite insole holds its loft across the full length of a big day, and the Mammut Swiss Design outsole finds purchase on loose gravel, hardpack, and everything in between. At just 330 grams, this shoe carries almost nothing while delivering the kind of underfoot comfort that keeps legs feeling fresher well into the afternoon."
