"What Our Gearhead® Experts Are Saying:""I wore the Sertig II Low Trail Running Shoe on a mixed-surface day that started on singletrack and turned into a scramble across wet granite, and the Swiss Design rubber sole kept me confident the whole way. The Air-Mesh upper ran cool even when the trail leveled out, and the pace picked up, which made the transition from hiking to running feel completely seamless.""Some days the plan is a trail run, and some days the plan falls apart into something better. The Mammut Sertig II Low Trail Running Shoe is built for both outcomes. The Air-Mesh upper and Vent-Mesh lining work together to move heat out and keep things cool when the pace climbs, while the EVA midsole absorbs enough impact to make rocky stretches feel manageable, whether you're cruising or grinding. The Swiss Design rubber sole is the detail that makes this shoe genuinely versatile. The lug pattern holds traction on loose dirt and slippery rock alike, so the shoe keeps up when the terrain gets unpredictable. At under 12 ounces, it disappears on your foot and lets you focus on the run, the scramble, or whatever the day decides to throw at you instead."
