La Sportiva KILO XTR Ski Boots: Ultra-lightweight performance for your ski touring adventures

Designed for demanding ski touring and ski mountaineering enthusiasts, the La Sportiva KILO XTR combines lightness, power, and comfort to support you throughout the season. Weighing less than 1,200 g per boot, this model stands out as a benchmark for skiers seeking an excellent balance between efficiency on the ascent and precision on the descent.

A touring boot designed for long ascents

Thanks to its wide range of motion from 68° to 70°, the KILO XTR offers exceptional freedom during ascents. Each stride becomes more fluid to reduce fatigue and optimize your performance on long approaches or steep climbs. The Tilt-Lock Lite system, compatible with thick gloves, simplifies ski-to-walk transitions even in the most challenging conditions.

Inspired by the world of competition, the 90° flip-up cuff significantly facilitates putting on and taking off the boot thanks to its three entry and exit modes. You’ll enjoy intuitive and quick use, ideal for technical outings as well as long days of exploration.

Power and precision on the descent

Despite its featherweight design, the KILO XTR impresses with its stiffness and support. Its shell and cuff, made of bio-based Grilamid® LF Carbon reinforced with long carbon fibers, ensure excellent energy transfer and precise ski control in all conditions.

With a flex rating of 120, this boot offers excellent support on the descent and allows you to confidently tackle powder, technical couloirs, or more demanding alpine terrain. The FORCE FLEX System™ enhances both support and progressive flex, while maintaining a natural stride during ascents.

The FORCE Closure System™ ensures precise and even tightening to perfectly conform to the foot and minimize pressure points. The 101 mm last provides an excellent balance between comfort and precision for long outings.

Comfort, grip, and efficiency on all terrains

The dual-compound FriXion Wave Alpine XTR sole improves traction during walking sections while maximizing shock absorption. It also limits snow buildup under the boot to maintain effective grip in all situations.

Compatible with insert bindings thanks to the Tech Binding + S4 Inserts™ system, the KILO XTR makes it easy to step into ski touring bindings and ensures fast, precise energy transfer to your skis.

Ideal for skis with a waist width of 98 to 100 mm, the La Sportiva KILO XTR will appeal to skiers looking for a modern, lightweight, high-performance touring boot capable of excelling on both ascents and descents.
