Forty Below overboots have been and continue to be, standard issue equipment in the coldest mountain ranges of the world since 1973. Everest, K2, Denali (Mt. McKinley), Vinson, Aconcagua, Cho Oyu, Annapurna, you name it, they've been there, keeping feet and toes warm and safe from frostbite.

These overboots are proven to work with almost every crampon and mountaineering boot combination on the market. Ultralight and packable, these are perfect for expeditions where weight and bulk are constant enemies. Constructed of 4.7mm neoprene, these also use a Velcro closure system that is easy to work with while wearing gloves.

Sizing Chart

To size: measure the end to end length of your boots. For proper fit, the overboots should fit snug but not too tight. If the sole length is at the maximum range of a size, go up to the next size to accommodate for the Neoprene insulation expanding at high altitude.
