G-Summit

The G-Summit is the new benchmark for high altitude technical mountaineering, developed to satisfy two needs: to be an extremely warm single boot for high altitude mountaineering and be a lightweight and precise double boot for extended expeditions in highly challenging climates. With its unique removable liner and thermal insole, the G-Summit is a customizable product based on the requirements of the user and the terrain/conditions of intended use.

Inner shell made with the patented Core-Wrap™ technology maximizes warmth while remaining ultralight
The BOA® Fit System makes it quick to adjust the lacing fastener - designed to be opened and closed while wearing gloves in cold conditions
Optional liner addition can turn the G-Summit into a double boot for increased warmth
Vibram® Dura Step compound offers the best grip for mountaineering excelling in low temps and wet terrain
The Ice-Tech™ tread is divided into two sections enhancing performance during ascents and hiking
Resoleable, to reduce environmental impacts
