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 designed 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. The S-Tech upper is a synthetic alternative to leather that provides durability and water resistance with a radical weight savings. It has a similar "memory" to leather, so it holds its shape over time once it's formed to your foot. A Kevlar®-reinforced integrated gaiter and tongue keep out snow and debris, and a quick-lace system makes life easier in frigid conditions or when you don't want to remove your gloves.

• Integrated Sock-Fit Plus gaiters and tongue are tough, Kevlar-reinforced S-Tech fabric for lightweight protection.
• Upper is KCN-Tech fabric, constructed from Cordura®, Kevlar and nylon for hard-wearing support.
• Outdry waterproof-breathable membrane is bonded to the external fabric to keep your feet dry and comfortable.
• Quick-lace system can be operated with cold or gloved fingers.
• Active Plus insole is made of fibreglass and polypropylene for cushioned control.
• Lightweight midsole has a medium density polyurethane heel and medial vertical grooves for cushion and support.
• Pentax Precision III outsole with Vibram Mont rubber compound for support and durability in extremely low temperatures.
• Compatible with hybrid crampon binding systems.
