La Sportiva Expands Ski Boot Lineup with the New Kilo XTR and Sender for Fall 2025

BOULDER, Colo. (Feb. 14, 2025)—La Sportiva, makers of the world’s finest mountain gear, today announced two new ski boot models for Fall 2025: the Kilo XTR and the Sender. The Kilo XTR builds on the success of the award-winning Kilo, refining its lightweight construction while increasing downhill power. The Sender, a new four-buckle freeride boot, is designed for big-mountain skiers who need power and control on the most demanding backcountry lines. 

"La Sportiva has a long history of crafting high-performance ski boots that balance lightweight efficiency with outstanding control,” said Jonathan Lantz, president of La Sportiva North America. “With each new model, we are refining our designs to push the limits of what ski touring boots can do. The Kilo XTR takes the performance of the Kilo to the next level,  delivering more control on challenging lines, while the Sender offers freeride skiers the stability and responsiveness needed for steep technical descents and rugged alpine terrain.”

Kilo XTR – Uphill Efficiency, Downhill Power

Built on the foundation of the award-winning Kilo, the Kilo XTR delivers enhanced control on the downhill while remaining lightweight and efficient on the skin track. Weighing just 1190g, the Kilo XTR excels in difficult terrain, offering a 68-degree range of motion for fast, energy-efficient climbing. A carbon-infused tongue increases the flex rating to 120, giving skiers a powerful, responsive feel for confident descents in variable conditions.

The boot’s Force Power Strap and Force Power Buckles allow for precise tuning of responsiveness and fit, while the Tilt Lock Lite System makes ski-walk transitions quick and seamless—even in harsh alpine conditions. The Force Flex System, featuring a Pebax® Rnew® tongue, enables a smooth, natural walking motion on the uphill, while the In-Axis Pivotal Joint optimizes efficiency on steep climbs.

A Frixion Wave Alpine XTR sole prevents snow buildup and provides traction when boot packing, while dual-compound rubber enhances grip in high-wear zones. Inside, the Ultralon high-density thermo-moldable liner delivers a precise, comfortable fit with excellent warmth and support.

The Kilo XTR retails for $849.

Sender – Freeride Performance, Backcountry Versatility

For big-mountain skiers who thrive on steep, challenging descents, the Sender offers a powerful freeride experience in a lightweight package. With a 130 flex and a weight of just 1480g, it’s one of the lightest freeride touring boots available, ensuring that long approaches and high-alpine missions don’t come at the cost of downhill performance.

Designed to seamlessly transition between the backcountry and the resort, the Sender utilizes a GripWalk™ outsole, making it fully compatible with alpine bindings. La Sportiva’s new Force Wrap System enhances the fit and features a Force Wrap Tongue constructed with a double layer, allowing for increased flexibility when in walk mode and maximum power transfer on the descent. With a 64-degree range of motion, the Sender climbs efficiently and feels just as natural on the uphill as it does charging big lines on the descent.

The $849 Sender features a Pebax Bio Based Rnew shell and a Grilamid Bio Based LF Carbon shell. A last width of 102.5 accommodates a wide variety of foot shapes, while the Tilt Lock FR System allows for quick, intuitive ski-walk transitions. 

Both the Kilo XTR and Sender ski boots will be available at select retailers and online at www.sportiva.com in the fall of 2025.
