The North Face Verto S6K Glacier GTX (2013)

The 6K denotes that the The North Face Verto S6K Glacier GTX is designed to be used at altitudes up to 6000m on Alpine mountains, and for that environment it has a good set of features. So you get Primaloft insulation inside to help keep your feet warm and this boot is also very light at 2088g (pair, size 11) – both features that make it great for Alpine use. The upper is made of synthetic materials and a high rand protects it from abrasion, while underfoot you get a very aggressive Vibram sole with well-spaced deep lugs plus a smooth area under the toe for better performance when climbing on rock. The fit is very comfortable with a slight tapering at the foot, and while it does not feel quite as precise as some boots it certainly feels ideal for use with crampons while crossing glaciers and climbing on high Alpine peaks. When walking on British winter mountains the high ankle cuff feels a little restrictive though and you don’t get such a smooth walking action as with other boots. It is a great choice for what it is designed for, but at this price and with this performance it is not the best for British mountain trips.

Upper materials synthetic, Primaloft insulation
Waterproof lining Gore-Tex
Sole unit Vibram Mulaz
Women’s sizes none
Men’s sizes 6-12
Weight 2088g (pair, size 11)


The The North Face Verto S6K Glacier GTX is a great boot for Alpine mountaineering, glacier travel and more challenging winter routes on British hills, but it offers more performance than most walkers will need on British winter hills.
