Sizing Notes
For boots: Add one half size to your street shoe size. You should be able to slip one finger behind your heel when you are standing up with the boot unlaced and your toes touching the front. If the boot is too short, your toes will get smashed walking downhill. Too long and your heel will slide up and down and give you blisters.

- I've had issues with foot fatigue for a number of years, especially on descents. I am super impressed with the comfort of this boot, have has zero issues with 4-6 mile approaches before tightening the laces for more tech terrain. - Noticed some comments/reviews covering warmth concerns. No issues climbing mixed technical routes on Colorado 14ers in negative degree weather using a single medium weight sock. (Everyone is different) - Out of the box I took them on a light 8 mile out n back for break in with the thought I'd need a couple of short trips to get them ready. No need, the boot was ready to go. - Awesome stability and a rigid sole for crampons. - Great ankle support, no heal blisters = happy. - Price was a concern, its a big investment. If you want a combination of support, rigid sole, durability and warmth... I'd say check em out.

Climbs great but runs cold
10 years ago
This boot is comfortable and light. The rigidity of the boot also means that it climbs great! I have no complaints on hiking or technical climbing performance. My only problem with this boot is that it runs quite cold. In Ouray, my feet were getting cold even though it was 35+ outside. Warmth seemed to drain through the soles into the ice. When I got back to the northeast I took out the filmsy insole they came with and put in the superfeet redhots. This improved the warmth considerably. Still not great, but I would be willing to tackle conventional alpine if I expected say 15+ temperatures. Overall I am happy with them but wish they were warmer. A note on sizing for those ordering: I have narrow feet and so la sportiva products in general work well for me. Size 46 fit me great. I also wear 46 in La sportiva's trail running shoes. In men's US dress shoes, I tend to wear about and 11-11.5. Hiking boots of other brands are variable for me. I might wear anything from an 11.5 - 13US.

Bought and returned after an extensive (failed) trial period. Buy a half size or more larger than your regular boot. My complaints are... they ran COLD. It was not uncommon to loose the feeling in my toes on peaks (Mt Washington, Eleanor, Rose, Stone (Lake of the Angels), Adams, Hood, and finally Rainier (DC)). Second concern was I could not seem to find a working combination of socks and liners to avoid heel burn. Eventually I started to tape my heels before heading out. Third complaint is they wear out quickly. Crampons beat up the edge and the tread wore quickly likely due to traversing exposed stone (...think Enchantments). I have nothing to compare these to so I supposed you can take my experience with a grain of salt (Despite a friend in AK having a very similar experience). In other news... they lace up nice, have a tongue insert for those feet, and have a good balance of rigidity and stiffness. They pointed well in everything in all conditions. They'll help you look the part! I'll try a different boot for this years attempts. I never thought to try an insert... a valid point.

Amazing boot.

I bought this boot more moderate ice climbing in Alaskan winters. I've used them about 10 times and in temperatures down to -5 degrees F. I've had warm toes the whole time. These boots paired amazingly with the Petzl leverlock crampon.

Sturdy but blisters!

I recently hiked Mt Rainer with a pair of used 43, I usually wear a size 10 running shoe. They were sturdy and had great ankle support but my toes were cold, it was about 15-20 degrees F, I wore two layers of socks, medium and light. My heels got nasty blisters in the first 30 minutes. I adjusted the laces and tongue but still had heel burn. Going up and coming down Rainier I got hammer toe trying to kick in steps and trying not slide down the mountain. These boots did not fit my feet well, maybe they fit others better.

Perfect fit but does run cold
8 years ago
This boot fits amazing. Requires virtually zero break in period. I got a true to size and I had zero complaints on the comfort. It does run a bit cold. Took these up Mt. Rainier and my toes almost froze off in conditions that were not that bad. I may trade in for the Baruntse's.

This is a VERY nice boot. the quality of the boot is obvious when you first open the box. I have not used them yet, but they feel great on the feet, really lock them into place, in a comfortable manner. For sizing I usually wear 11.5 - 12 , and I got a 46, which is 12.5 or something. I would not have wanted to go any smaller, but I do have wider feet. Anyway, as of now I say they are worth the big bucks, we will see how they perform. Im expecting greatness.

I've been using Trango Cube and Makalu boots for 10+ years. I got these for NE winter boots, the Makalu get cold below 20F. These fit better, are lighter and almost as nimble as the Makalu. The sole is really stiff. I'm size 12 and bought 47/13 and fit is great. Normally I buy the other boots in 46.5 which is good, but I can get some toe bang kicking a rock. Not too hot wearing around the house or in moderate 30F temps.

Unbelievably comfortable

Best boots I've ever climbed ice in. Super comfortable on the approach. Excellent fit. No blisters even on the first several mile "break-in" period. Retain crampons with no issues. Excellent--wish I bought them years ago!!

These boots performed great on 14ers, light and comfortable. Go at least one size up to wear with warm socks, break them in and adjust laces in order to avoid hill burn.
