La Sportiva  G-Tech Mountaineering Boots

I've used these for a little over a season of ice climbing and though they are the best boots I have ever climbed in, the durability is very poor. Not only have the toe welts cracked, but the cloth strips that the boa system is sewed to has completely ripped on both boots. It seems really odd to design a shoe with a BOA closure and then to have the BOA cables running through thin strips off cloth that are sewn into the boot. The BOA system essentially pulls the internal components of the shoe apart at the seams. I've put in a request for a replacement via warranty hoping this is just an issue with my given pair and not a major design flaw.

I spent the better part of the ice season on these wonderful boots. Would recommend 100% I have tried different boots including the P techs and I really love the fit and performance of these so much more! The Boa dials in fit, and they are stiff enough to tackle anything I can throw their way. Beautiful construction. I have used them on steep ice and mixed, in negatives to plus 40. I’ve done 2 hour approaches in them, and leave them loose and comfy for that. They feel like little Ferraris on your feet. Crampons- I had to add a few clicks on the tension bar as compared to the Nepal last. The fit- I’m a 46, narrow volume and wide toe. These boots are tailor made for my feets. Way better fit and walking AND climbing performance than the P techs in my opinion. I love these boots!! Spendy but very much worth it. They won’t let you down.

Love these boots! Light and super comfortable for Alpine hiking/mountaineering and especially ice climbing. Boa adjustment is perfect and crampon compatibility is ideal

I was sized at the La Sportiva store for a 38 but REI doesn’t carry anything lower than a 38.5. Really too bad since most women require the smaller sizes. I shopped around at other local gear shops and the lowest they carry was a size 40! I bought the 38.5 and will try thicker socks and maybe inserts to see if I can make something work else I will have to buy the smaller size directly from La Sportiva. I thought REI had expanded their size range to be more inclusive but I keep running into this problem again and again.

Super lightweight and super comfortable boots with a slim profile and awesome boa system that allows you to tweak the fit when you're ascending or descending. Works great with full auto crampons, and the built in gaiter is excellent. After years in big heavies (Eigers, Nepals), making the jump to these made me nervous, but it was well worth it. Just got back from climbing a well known Cascade volcano with a long approach and a long day of steep snow/ice/glacier travel, and my G-techs were the G-she-it!

Wore these for the 2023 ice season, one of the best and longest ice seasons in UT on record. Probably got around 60 pitches of ice in, and these were phenomenal in every regard. Interface flawlessly with the Petzl Dart. Great mixed climbing boot as well. The quick adjustment with the external boa dial is how every ice boot should be. Allowing for a nice loose comfortable fit for belays and casual approaches, and a quick adjustment to get them nice and tight for climbing. Easy to adjust mid-pitch too if you need a slight tweak. Great rigidity, almost 0 heel lift due to the sculpted heel cup that locks you in really nicely. A little chilly on really cold days, but I did fine for the whole season with stock insoles. Might help to find a warmer insole and create a thicker barrier of insulation between your foot and the ground, otherwise flawless.

Upgraded to these from my North Face Torre Eiger boots. Very happy. They are significantly more adjustable than my previous boots and much more comfortable and precise, and finally a boot that doesn't give me blisters. I should have spent the money on these from the beginning. Great climbing ice or drytooling and decent for approaches for this style boot. Warm enough for cascade climbing. Worth noting that this boot was also recommended to me by a lot of professionals at an Ice Climbing festival.

Amazing boot for mixed and ice climbing adventures

Easily the most uncomfortable climbing boot I've ever used - the boa doesn't allow for precise tightening, and creates serious blisters on both my heals and top of my foot (something I've never experienced before) on event the shortest of approaches. If you have a roadside ice line or are skiing into your destination, could be okay. Otherwise, any other option will be far better.

This is a short-term review. I just got those over a week ago and climbed in them for 2 days. For me, they are the best of both world. A good compromise between warmth and functionality for those of you who are on the hunt for a warm and technical boot. I've mostly been winter ice and mixed climbing with the Trango Ice Cube which will always have a special place in my gear shed, but these new bad boys are definitely a contender for a new favorite. I climb in Quebec where cold and humid weather is part of the game. I got them in size 42.5 like all my other LaSpo Mountain Boots. The first think you notice is how light they are. It almost feels like you'll have difficulty to kick in the ice, but with crampons on, it's fine. Actually, it's way more than fine, it's amazing! For their weight, they certainly provide some warmth, they feel warmer than the Trango Ice Cube. They are probably somewhere between a G5 and Nepal. Another crazy thing about those boots is how easy it is to loosen them up. I really like to have the BOA system outside of the boot. It will be amazing for multi-pitch. For a non-goretex boot, they seem pretty waterproof. I tested them out literally stepping into 6-7 inch of water and my feet stayed dry. I can't tell much about their durability, but the light fabrics certainly isn't as tough as leather.
