The new benchmark for high altitude technical mountaineering. Ideal for ice climbing and climbing big walls, technical treks in winter conditions and staying in extreme places at low temperatures.
G-Summit was developed with the aim of satisfying a double need: an extremely thermal product for high altitude mountaineering and a surprisingly light and precise double boot for expeditions in highly challenging climates.
In fact, thanks to the special removable liner, G-Summit turns is a customisable product based on the thermal requirements of the terrain and environment of use.

I did one tour with them to 3x4000m in the alps in September. Had super cozy feet. Size is very different with/without the liner but since I am planning to wear them only with the liner in anyways this doesn't matter.

Impact Break System Mountaineering
The innovative system is applied to the sole to absorb negative ground impact, help traction and improve grip downhill.
Created and developed by the R&D department at La Sportiva, it offers real advantages during racing by reducing negative ground impact. The unique position of the lugs allows as many of them as possible to come into contact with the ground, for maximum impact absorption.
