La Sportiva Kilo Ski Boot - 2025 - Women´s

Kilo Ski Boot—ultralight for mountaineering ascents without compromising downhill control

“The Kilo Ski Boot is a game-changer for ski mountaineers. It’s unbelievably light at just 1000g, making ascents feel easier, and the Grilamid Bio Based LF Carbon™ shell adds stiffness without the weight. The Force™ closure system keeps my foot locked in on the descent, delivering confidence even on technical lines. It’s the perfect blend of uphill efficiency and downhill performance."

The Kilo Ski Boot is crafted for serious ski mountaineers who value ultralight ascents without sacrificing downhill control. La Sportiva´s innovative use of Grilamid Bio Based LF Carbon™ in the shell and cuff creates a boot that is both incredibly light and impressively rigid, delivering performance in both directions. The new Force™ shell closure system allows us to dial in the perfect fit, distributing pressure evenly for comfort and control. At just 1000 grams, every gram has been optimized for functionality, making the Kilo the ultimate choice for demanding ascents and descents in technical terrain.
