Scarpa raises the bar for lightweight alpine climbing footwear with its Men's Rebel Ultra GTX Mountaineering Boot. And just because it's super light doesn't mean it holds back in protection against Mother Nature's fiercest weather. The waterproof Gore-Tex Insulated Comfort membrane provides extreme warmth and waterproofing against the snowy cold you love to climb over. Scarpa's innovative tongue and gaiter system blocks snow and debris from entering your boot, and it provides an excellent fit by minimizing bulk. You'll move quicker and easier too thanks to the boot's flexible cuff.

The Rebel's Cordura and Kevlar upper fabric keeps the weight down and the durability up so you'll have this ultralight boot for a long time. And the carbon-fiber insole only complements the Rebel's durable and lightweight feel. Its tri-density PU midsole provides long-lasting comfort that resists water so you don't get that moist feeling in the boot on multi-day excursions. You'll feel secure with your footing over technical terrain thanks to Vibram's TT Lite sole, and the Rebel also has TPU inserts for automatic and semi-automatic crampon compatibility when the mountain takes a vertical ascent.

Great all around performance boot

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

I haven't achieved the warp speed of Uli Steck in any case, but these boots make me feel like I have wings on my feet! Their weight is unrivaled and the quality and craftsmanship in every detail is exceptional. They are stiff and climb rock and ice beautifully. The low profile helps considerably with precision footwork and the lacing system locks my foot in really well without constricting. The gaiter system is easy to get in and out of with the pull tabs and keeps snow, water and trail dust out really well. I've used them for waterfall ice, mixed, alpine ice and rock routes. Nice to have the ability to strap a pair of step in crampons on and feel like they are integrated into the boot. This boot is stiff which makes it performance on rock excellent. I've not found the stiffness to compromise comfort for long approaches at all. I size up a half size from my street shoe size so I can wear a thicker sock. I've found them to be quite warm, but not as warm as the Phantom Guide for pure ice routes in the winter.

FINALLY! These boots are ridiculous. They are the lightest boots that I have owned, and they have a heal /toe welt for crampons and a built in gator. Ueli Steck, who was the backbone of the design nailed it with these. I have been using them this fall for mixed and ice routes in Rocky Mountain National Park and have been blown away with their performance.

How do these compare to the Guides for ice climbing and also warmth.

As far as an ice climbing boot goes--the Rebel Ultra GTX is in a class of its own...probably the finest ice boot currently on the market, and a real game-changer for harder ice and mixed in remote areas. You should check out Dane's review here:

The guides on the other hand, are much warmer than the Rebel Ultra GTX's--but you pay for that in size, bulk, and weight. It's a total trade-off between the two of them, so picking the right boot would depend heavily on the type of use you have intended for them.

Maybe you could help me out by answering the following questions:

1. Where do you climb?

2. What months of the year would you be using these boots?

3. What is the coldest temperature you would expect to be climbing in these boots?

If you can give me the answer to those questions, I can help you with a better recommendation.

Obviously super light weight. How warm are these compared to the Phantom 6000? Would these be warm enough for Ruth Gorge?

Hey Drew,

If you haven't already, go check out Dane's excellent writeup of the Scarpa Rebel Ultra. He uses them as a 4-season single boot, but in the comments says that they are not as warm as the Nepal Evo (which, consequently is not as warm as the Phantom 6000).

Check out his review here:

So, in summary--note as warm as the Phantom 6000, but much, much more technical. Many people (including Dane) are using them for full winter ice climbing, but that doesn't necessarily mean that you should. If you need warmth, go for the Phantom 6000.
