Mini-Expedition to Mt Langdak (Nepal).

The G2 SM proved to be the perfect shoe. Challeging conditions, -20C, wind, hard ice. To BC long day on gletchers (9/10h) using crampons, easy going feet keep movememt not constrained by straps. BC to HC same. Especially the easy system to put the double shoes on and off is a huge advantage! Another one is the integrated gaitor. The finetuning 1mm is 1click makes it highly adaptable during the tour. Summiting included snow, ice and rock. In the steep icepart the stiffness is suberb. At the same time shape, weight and sole makes it as if you go on your D boots. Conluding suberb shoe, very glad I choose this brand/type.
