The North Face’s Verto S6K Glacier GTX is designed to be used up to 6000m on Alpine mountains and glaciers, and if you grab it between toe and heel and try to bend the sole, it’s clear this is a true 4-season boot because there’s plenty of stiffness in that sole unit. Inside the boot there’s also a layer of PrimaLoft insulation to help keep your feet warm at altitude. The upper is made of synthetic materials, and a high rand protects it from abrasion. The outsole is a very aggressive Vibram unit with deep, well-spaced lugs to prevent clogging while maintaining a good bite into the snow or ice. At the toe there’s a smooth area for better performance when scrambling, mountaineering or climbing on rock. On the foot, it’s noticeable that the toe is slightly pointy, although it’s not quite as precise in this area as other boots for climbing. The The North Face Verto S6K Glacier GTX generally feels good for walking on glaciers, as the name suggests, and would be ideal for general winter mountaineering. It’s also very light at 2098g (pair, size 11) for its performance level, which makes it great for Alpine use. However, when used for winter walking on British mountains the high ankle cuff feels a little more restrictive than others, and the general walking action isn’t quite as smooth as others.

The The North Face Verto S6K Glacier GTX is a great boot for Alpine mountaineering, glacier travel and challenging winter routes on British hills. But if you won’t be tackling this level of terrain, it offers more than you need.
