What Our Gearhead(R) Experts Are Saying:"I keep a pair of these in my car for after long winter hikes, and slipping them on the second I'm back at the trailhead feels incredible. The microfleece lining and thermal foil kept my feet warm even standing around in the cold packing up gear."Cold weather doesn't stop once the hike ends, and the Mammut Sender Moc Low Boot is built for everything that happens after. Kick off a stiff hiking boot at the trailhead, and the laceless sock construction slides on in seconds, adapting to your foot for a snug fit whether you're packing up the car or wandering into town for a warm meal. Mammut LOOPINSULATION, made from industrial rope offcuts and recycled rPET, locks in warmth while a microfleece lining adds next to skin softness against the cold. A built-in thermal reflective foil between the upper and midsole bounces your own body heat back toward your feet, and the Mammut Swiss Design outsole keeps you steady on frosty sidewalks and slick winter streets long after the trail is behind you.
