Salomon S-Lab X Alp Carbon GTX

This is the first ever low-cut mountaineering boot.

Brand: Salomon

Model: S-Lab X Alp Carbon GTX


Protection

If you like to backpack in trail runners, then you’ll love climbing mountains in these. An integrated, padded Lycra gaiter over the low-cut synthetic and Gore-Tex upper creates an impenetrable barrier against snow, rock, and water. A rigid midsole shields against sharp rocks and provides a stiff platform for universal crampons. A 1.3mm-thick synthetic upper and Gore-Tex membrane (there’s no insulation) kept us warm down to 5°F in California’s White Mountains. What you don’t get: ankle support and protection.

Support

We pushed these boots on mixed terrain from Alaska to Chamonix, lugging packs up to 50 pounds. They delivered. The midsole includes a stiff, carbon-fiber chassis that’s torsionally rigid, yet flexible at the forefoot for comfortable walking. The secret: horizontal cuts in the middle of the frame, which encourage flex when the sole is weighted, yet maintain stability while edging.

Durability

These boots are tank-tough, thanks to a rubber rand and thin, flexible TPU reinforcements.

Weight

They’re crazy light—and comfy—for mountaineering boots.
