About Garmont Xena Boot: Hi I’m Paul Parker, Garmont Ski boot product manager. This is the Xena. The Xena is the sister to our Endorphin. It’s a groundbreaking free-ride boot. Skis like an alpine boot, walks like a ski mountaineering boot. It has interchangeable soles that satisfy two norms. This is the alpine touring norm sole and we have an alpine norm sole that you can use when you step in alpine climates. Four buckles, EU constructions, power strap, fully thermoformable G-fit liner.
