Forty Below Synthetic Camp Booties

Forty Below Camp Booties

Forty Below makes synthetic camp booties ($69) that are great for winter camping and mountaineering or for just wearing around the house. Cold feet no more!

Picture this. It’s winter, and you’ve been snowshoeing or backcountry skiing all day. Your socks and boot liners are wet with sweat and you need to change out of them soon after you find a campsite or else you’re going to get chilled. After that, you still need to erect your shelter, dig a kitchen, melt snow for drinking water, cook dinner, socialize and then sleep for 10 hours.

That’s where Forty Below’s Camp Booties come in. They’re insulated nylon booties with a synthetic fill and a removable insole. You can wear them with a fresh pair of socks around camp and your feet will warm right up. The insole is thick enough that your feet will stay warm, even if I’m standing directly on packed snow, while cooking dinner or melting snow for drinking water.

The bottom of the booties is made out of rubber with a dot shaped texture that provides limited traction, but enough to get around camp and for taking care of business at night.  If you need more traction, you can also take the insole out of the booties and wear them inside your mountaineering or ski boot shells.

The booties come with ribbon lacing to provide a more secure fit and run through fabric loops sewn along the sides and around the ankle. Forty Below doesn’t use any metal or plastic buckles for this, so you can that can wear them in plastic boots. Additionally, you can take the insoles out and wear the booties in your sleeping bag to keep your feet warm.

In addition to camping with these booties, I’ve also been wearing these them at home around the house. Plus, since they’re synthetic you can just pop them in the washing machine and drier to clean them. They really are a nice multi-use item.

The booties weigh 10.3 oz in a size large so there is weight penalty for bringing them on an overnight trip, but if you’re going on an expedition or plan to sleep overnight for a few days in a cold cabin (or even at home) , I’d seriously consider bringing a pair of these booties along.

    I bought a pair of the old style without the lacing and planned to use them with thick socks, so I bought them Large. Alas they are a bit too big. Anyone want to buy a pair of these in Large? Very good condition.

  2. Phil,

    Great tip, we're looking into the 40 below.

    Laura and I just picked up some climbing gear today and we want to do an ascent/overnight/ice climb.

    I know its a little late in the season but we climbed Hi Canon on Sunday and there were definitely a couple of places where it'd be fun to set up a top-rope belay. We aren't quite ready to do test climbing at Frankenstein, we want to mix it into an overnight 4,000 footer adventure.

    Do you have any suggestions for a 4,000 footer that has a really difficult vertical and icy summit approach? Maybe mt. isolation?

    Basically I want to sleep out saturday, get up early, set up a top rope and practice.

  3. Isolation is remote but not a hard ascent. One of the trickiest 4,000 footers with a fun cliff is Osceola, coming from East Osceola. That's not that far from the trail head. Square ledge is another great location, on the back of Mt Passaconaway, the Ammonossuc trail up to Monrose from the base station is quite steep, the AT up Mt Webster, and either North or South Hancock. Your best bet might be to call Sara Reeder or David Lottmann at the EMS Climbing school and get their advice. They can probably steer you to some excellent spots. Just call George at the school.

    Actually Flume might be a good choice too.

  4. Hi Philip!
    I currently use the Salomon Toundra Pro boot for winter hiking, which I believe you do also. I’m considering the purchase of a winter camp bootie for when I’m sitting around and not hiking. How would you compare the warmth of the Forty Below camp bootie to the Salomon Toundra Pro. I’m trying to figure out if my feet will stay warmer if I just keep the Salomon boots on, or if I switch to a bootie. Do you have experience with other winter camp booties? If so, how would you compare their warmth to the Salomon Toundra Pro.
    As always, thanks so much for sharing your experiences and reviews!

    • If the toundra liner is dry it will as warm as the bootie.
      But unless you wear a oven roasting (vapor) barrier bag over your foot, it won’t be.
      The value of the bootie is that it will be dry, it has a sole, and it’s lighter than a hiking boot. Any insulated booties with soles will do.
      If you don’t want to use a vapor barrier sock, use a boot with a removable liner that you can sleep with to prevent it from freezing, like
      Even then, the liner will be damp when you take your boots off in camp. Make sense?

      • Hi Philip,
        Yes, I think I follow what you are saying.
        I was just wanting to get a sense of how warm camp booties can be. If they can keep your feet as warm as the Toundra when the Toundra liner is dry, that’s just awesome, because I’m really impressed with how warm the Toundra keeps my feet. It sounds like booties are quite warm.
        Thanks for your help!
