La Sportiva  Aequilibrium ST GTX Mountaineering Boots - Men's

I bought these boot 6 months ago hoping they would be great boots. Upon receiving them I was excited to start wearing them and try them out. Many guys I work with have La Sportiva boots and have said how nice they are and how well they hold up and keep their feet dry. The first couple months were great. I loved them. They were light and have a lot of support. I would have given a 5 star review then, but I waited and some of the lugs started falling off and now there are multiple lugs missing on both boots. Everything else if holding up well except for the bottom of the boots. This it why I feel they are only 2 stars. See pictures for bottom of boots.

I climbed with these for 6 hours in winter-like conditions (deep snow, light snow, icy snow, rock, dirt, scree, steeps) up to 13,500 Feet with 30 Mph gusts with sub freezing temperatures and negative windchills. They walked comfortably, climbed with excellent traction, post-holed in to the snow without cooling my feet and descended with extreme confidence. The lugs are revolutionary, they remind me of the superior traction that I get from my Solomon Cross Hike GTX Lows (my go-to summer 14er shoe.) I have no complaints with this boot for 3 season alpine use and I really look forward to the next climb. Time will tell if they can handle true winter conditions. I think they run true to size. These will likely be my go-to fast and light shoulder season alpine boot.

Very comfortable spring mountaineering boot. Semi-automatic crampons work great for secure fit even on steep terrain when front-pointing firm snow. Trying them on around the house I thought the toe box seemed a little tight but once I started moving around in them, that all went away. I size my winter mountaineering boots up by 1/2 size but went with my street shoe size for these in case I find myself on technical rock and want a snug fit; seemed like that was the right call. (45.5 for my size 12 street shoe fit). Need to get more mileage on non-snow terrain, but suspect they’ll at least be better than plodding across rock/talus in Evo Nepals

Very promising and appealing boots. I got these for winter trekking in the snow and they are almost perfect for me. The deep lugs look like they will clear material effectively and despite the support the boots wall well. The fit is good in the heel and mid foot, however I have a wide forefoot and have to send them back for a bigger size. One of these brands needs to step forward with an Altra style toe box because although these are wider than a lot of Sportiva footwear, the diamond point in the toe box ruins it for some of us. I can’t speak to durability yet but they seem well made.

These boots are great. I recently summited Mount Baker, Eldorado Peak, and Mount Rainier in these boots and they were great. My feet would get cold during longer periods of inactivity but as long as I was moving I was warm. They were great for approach hikes (common to PNW mountains) but rigid enough for postholing and kicking your way up icier slopes. Can't recommend enough for late spring/early summer mountaineering on lower altitude climbs.

I bought this boot a year ago and have used it extensively. I also have the trango trek gtx to compare to. Most comfortable goes to A equilibrium. It is a wider boot in the same size and the toe box is more generous. It's also less stiff and more comfortable for hikes and approaches. The sole is amazingly soft and cushioned. The trango climbs better -probably due to its narrower stiffer build- and is more comfortable in crampons. The trango also wins in durability. Those big lugs and really soft sole on the Aequilibrium wore out WAY faster. Overall, if you do more hiking goes for the Aequilibrium. If you do more climbing I would lean towards the trango

After 250 mountain miles: Best overall comfort and grip! Still going strong. Have tried out ,for many years; more and less expensive, major and non-major brands. These are mid-range expensive, comparatively, universal, and better. No metal lace guides or hooks on the lower half, to get smashed, bent, snagged, caught on your crampon, or snowshoe mechanisms and straps. More comfortable now than ever before. Bought fancy insoles and ended up using them in my hikers. Comfort from the get go. Broken in. Almost Therapeutic! Unlike others. I have yet to need to apply any waterproofing, if not yet guessing never. Rigid and yet not too rigid, they're great! Traction and grip, the best! My toes got cold one time, when I stopped in -30 F, for half an hour long lunch. And were fine when started moving again. They are really just like the specs and description say they are. A rare enough thing in the World. Thanks REI and La Sportiva!

These are some seriously awesome boots. Extremely light weight, no question these will comforably allow you to trek 20+ miles. Construcion is clearly top notch. I can't find a single quality control flaw anywhere. I really like how stiff they are, but not quite full on shank stiffness of the likes of the Nepal series. I don't really write reviews, but wanted to share how pleased I am w/ these boots. Highly recommend if price is not an issue.

Although I only have one trip under the belt with these boots, I was impressed with how they felt on my feet and how they allowed me to move easily on variable mountain terrain. They are light, felt solid with strap-on crampons and worked well on loose scree, talus, and solid rock, too. Not overly hot in summer conditions and did well to keep feet dry in wet snow and for stream crossings.

I have only used these boots twice, but so far have performed well. Light, nimble, comfortable as all of my other La Sportiva’s. I have been using these for winter hiking/scrambling in AK and they have kept my feet warm and dry in single digit temps. Not only does the Gore Tex work well but the outer material sheds moisture to prevent it from absorbing into the boot. This is the first pair of boots where my feet are bone dry at the end of a winter mountain hike. My only problem is that the laces seem to come untied at some point which normally hasn’t happened with La Sportiva laces. Not a deal breaker as I can double knot but I am surprised this wasn’t noticed during testing. Who knows though, maybe its just my foot geometry/gait. Anyway, highly recommended light technical boot for winter day outings or shoulder season where you may or may not need crampons.
