Stellar II is the boot dedicated to all round ski mountaineers looking for the best mix of performance on the ascent, descent and comfort.

Its ease of fit and use also make it a boot suitable for newcomers to the world of ski mountaineering who are looking for a multi-purpose, high-performance tool. The internal shape is anatomical for perfect foot positioning and maximum comfort.

Solar II is a comfortable, safe and fast ascent boot, performing and progressive descent boot.
