Forty Below Camp Booties™



The synthetic insulated camp bootie for mountaineering, winter camping, and even around the cabin, hut, or house!  Now your feet and toes can be nice and toasty after a hard day on your adventure!  These will be a favorite for all of your trips, year-round!  The Forty Below® Camp Booties™ are insulated with a continuous filament polyester fiber, so they dry fast if they get wet.  They also provide insulation even if wet, as compared to down/feather insulation which provides no insulation when wet, plus may not ever get dry again during a trip. This synthetic insulation goes completely around and under your foot.  The 5/8” wide ribbon style lacing goes over the top of the forefoot and around the leg, to tie in the front with a bow.  It helps provide support and control on your foot, no more floppy booties!  They are very compact, and superlight at only 10 ounces per pair size medium!

Specs Sizing Reviews

The sole is made of a thin waterproof unique rubber, embossed into a fabric with a small dot pattern, that stays flexible at 40 below and sheds snow easily. The lower side rand is made of Cordura nylon that is waterproof coated.  Taffeta nylon upper, and taffeta nylon lining to make them easy to take on and off with wool socks on.  Drawstring with cordlock top closure.  A very helpful feature is the removable closed cell foam footbed, so you can wear the Forty Below® Camp Booties™ inside the plastic mountaineering or ski boot shell when it is removed, helpful your when boot liner is drying.  Machine and hand washable.  Air or low heat dryer for drying.

Bought a pair for Kilimanjaro and they were incredible, even outside at 19,000 feet. I wear them indoors and outdoors, and liked them so much I bought a pair for my boyfriend. Synthetic makes the most sense when you're outdoors as they dry much more easily than down. Not only is synthetic the warmest but it's also great for us as we're both vegan and don't buy or support down fillings. Hands down, great boots.

These are warm and comfortable. Only complaint is that the foam liners can slip around a bit inside when you walk around causing your foot to hang over the edge. I was also on the line between Large and XL so I went a size up after reading the reviews. The XL's ended up being like clown shoes so I sent them back and bought the larges which fit perfect.

Good quality but just not warm enough. Wore in 0 degree and minus 10 degree weather and my feet were barely warm enough. Needs more insulation. Pretty expensive for average performance.

I love this bootie. Used them on Aconcagua, but even more so on around my freezing cold home! My one critism is that I think the Mediums run small... them fitting a size 10 would be a stretch I think.

Love these things. Used them on May 2010 summit attempt with winter-like weather. At Camp Muir these were sweet. Inside feet stay toasty without the boots or sweaty liners. Slip these into the boot shell to venture outside into the snow.

Worked great. Never cold. Helped to keep feet warm in the bag before removing. I bought these a size bigger than I should have thinking it wouldn't matter (my size falls in between) but they were sloppy walking in camp so based on my own experience; I would buy at exact size or smaller if in between.

These are the Only camp booties to own. Synthetic materials will stay warm no matter the conditions. I just got back from a climb in Colorado with temperatures near 0 degrees F at night and my toes were warm as toast. Priced right too!
