Rugged but featherweight boots for light-and-fast alpine missions. Inspired by the boundary-pushing mountaineer Ueli Steck, the innovative Ribelle Tech is an ultralight hybrid boot for alpinists or mountain guides who prize precision and lightness for a straight shot from valley floor to summit. Combining elements of trail running and mountaineering footwear, it offers incredible agility, control and grip along with big-day comfort.
