The North Face Men's Nuptse ThermoBall Bootie IV has changed your perspective on what "versatile" means. This boot can go from bumming around the basement on Sunday to basecamp in no time. The recycled ripstop upper resists water, and the ThermoBall insulation acts and even looks like down insulation, providing lofty warmth equivalent to 600-fill down. Unlike down, though, it stays warm even when it gets wet, so you have no excuse for not shoveling the drive or making coffee at basecamp. The IcePick temperature-sensitive rubber pods on the sole gives you traction on wet or slick surfaces, and won't shred your tent floor. The Northotic footbed and the injection-molded EVA midsole work in tandem to provide comfort if you are walking around for a while, and the internal ankle-securing elastic and collar drawcord lace with barrel lock make sure the bootie stays up, so your ankle stays warm. Warm and happy feet are a beautiful thing.

Here's what others have to say...


Exactly right

  • Familiarity:I've put it through the wringer
  • Fit:True to size

I live in Jackson Hole, WY. I wear these booties at least part of every single day in the winter. They're warm and the design and the molded sole work well for errands and chores outside. The sole is a bit bulky in a pack, but I cram them in even for a day of side country skiing at the resort. They're worth it and the end of the day.

Size seems OK, I like this kind of footwear a bit loose.

I'm going to buy a second pair and stash them, just in case a puppy or a spark gets to them.


Sex appeal

  • Familiarity:I've used it several times
  • Fit:Runs large

I'm not a sexy guy by any stretch of the imagination, but when I wear these boots...I feel sexy.

I have been told to order one size larger than your original size.
