All About Overboots

Forty Below® makes insulated boot covers which are also called overboots.

For over 40 years now, we have specialized in developing and making many different models of insulated boot covers, often referred to as “overboots”, which have been trusted and used on the world’s highest and coldest places.

Our mission here at Forty Below is happy and warm feet!

All of our Forty Below® overboots and products are still made in North America, and use the very best materials available from around the world, with skilled hand-made craftsmanship.

Most of our overboots are designed and intended for wilderness use, primarily for mountain climbing, backcountry skiing and snowboarding, snowshoeing, and wilderness fat tire mountain bike, and multi-sport events and racing.  One of the key cornerstones of our products is that they are stretchy and easy to put on and take off. This is very helpful when it is cold or if you are at high altitude! They are also very easy to repair, and this is helpful as overboots get a lot of abuse from crampons, equipment, and terrain.

Forty Below Ltd. makes several different designs and models to fit a wide range of uses, including fitting the entire range of mountaineering boots available, Alpine Touring ski boots for backcountry skiing and ski-alpinism, Snowboard boots, Lightweight trail running and hiking boots for snowshoeing, and bicycle boots/shoes for fat tire mountain biking. We can also make custom boot covers on request.
