So I am interested in getting the new Sportiva g2SM's but was wondering if anyone has had any firsthand use/ reviews.

I am torn between getting the Baruntse or the G2's.
My toes do get cold and this year I have been trying the vapor barrier system to try and keep them warmer (unfortunately it hasn't been a very cold winter thus far).
Obviously the baruntse is the warmer option but its also like 5LBS per boot in a size 48!! and that adds up significantly if Im logging higher mileage.

The sportive review claims the G2 is very warm... warmer than spantek but, has anyone put this to test? They seem so light that I wonder how much insulation they could actually have.

Here are my activities and location. More mountaineering style climbing and trekking with light ice climbing. so Im def not doing WI6-7 and sitting at a belay for hours. Maybe doing some WI2 WI3 climbing. Most of my hiking and climbing is in the Whites in NH or up in Maine. Obviously the weather on washingon can be all over the place.

Id love to et into more serious mountaineering with a possible trip to the Cascades this summer.

I love the ease of use of the Boa closure system (its what I have on my snowboard boots)but just am worried about the actual warmth of the boots.

thanks for your input
cheers

Never even held the G2SM in my hands, but a couple things can be deduced from the marketing material:

  • It's being billed as a 7000M boot. The Baruntse is billed as a 6000M boot. So, LaSportiva is very confident that the G2 is a warmer boot. How much warmer? About 1000M worth. Some of that will be due to the integral gaiter. Some of that will be due to thicker insulation.

  • The G2 is also 20% lighter than a Baruntse. The tradeoff here will obviously be durability. The Baruntse is the Mack Truck of alpine boots. The G2 will be like the Porsche Cayenne Turbo.

If you've got money burning a hole in your pocket, try out the G2. But it's definitely not necessary for your objectives.

On the flip side, if you're on a budget, try and find a pair of older Sportiva Nuptse boots. Those were my double boots for years and I did tons of snowshoeing/backpacking and mellow ice (e.g. Trap Dike) up in the Northeast with them. Those are the boots Steve House took up the Rupal Face of Nanga Parbat.

I've also never even held g2's, but I have a pair of Baruntse and they are super warm. My feet were comfortable when it was -35 degrees while I was in Alaska last winter and I have no complaints about them for ice climbing in New Hampshire this year, my feet usually sweat in them, but I'd rather be too warm than too cold.

Steve House definitely was wearing Spantiks on the Rupal Face.



Check the video around 9:35.

No, he wasn't. He wore Nuptses. Watch the video again. He never actually claims he wore the Spantiks.

Being a sponsored climber means keeping your sponsors happy, and if they tell you to talk about a different boot, you talk about a different boot. The Spantiks had recently been released and they wanted to drum up sales, hence that video.

But don't take my word for it. Just look at the summit pic:



Or his Instagram photos...

Clearly not Spantiks. Nuptses with G12 hybrid crampons.

I've checked out the G2.

It's worth the money IF you need that much boot. The fact that LaSportiva used the Boa lace system should tell you the fit is amazing with none of problems the early Boa laces had. I thought the best part of the boot was the fact you can loosen and tighten the boot easily during a long route.

Haven't worn them outside so can't say how warm. The G2 is light

Yea My main concern is the warmth because my toes have a tendency to get pretty cold but if I don't have to lug around 10 LBS of boot that would be fantastic. I'm 6'6" 215LS so that's enough to lug around as is especially with my pack full of gear and I do love the idea of the Boa ties and not having to lace up and re-tie with cold fingers. The G2 is pretty expensive. Damn these hobbies. Photography and climbing are not a poor mans games I guess.
Thanks for everyone's input.
Still hoping to hear from someone that has actually worn G2's in the cold.

If you go to the Whites a lot check out IME, they have them in stock. Chris Miemiec

For what it's worth summer climbin in the cascades doesn't need more than Nepals. In fact anything more than Nepals and you'll be kicking yourself...with sweaty feet. So I wouldn't take cascade summer climbing into consideration when looking at G2s Thatcher

Hell if it's north cascades the nepals are still too warm for me in the summer. I have to do produce bags over my liner socks to keep from filling "colder" scarpa rebel pros with sweat.

If cascades means a glacial slog at the guided group pace on Rainier though Nepals would be perfect.

True. Nepals are even overkill for most cascade climbing. I mostly use my trango s evo. I wouldn't want to do something like Liberty Ridge in anything less than Nepals. But I do have cold feet. Did rainier a few times last year in my trangos and couldn't feel my toes for 3 months afterwards. Thatcher

OGE in Vermont has them in stock as well.

The G2 in a lot of ways is a lighter version of the Spantik from what I can tell. Holding them in person the difference in weight between the two is pretty impressive for sure. The advantage of the G2 is indeed on longer trips where the weight savings means less fatigue and the removable inner boot means no cold feet in the morning.

I think for type of climbing you like to do they will be plenty warm. Other things to consider: warmer socks that fit well is a huge help, and the red hot superfeet insoles help with heat loss through the bottom of the boot when standing around on cold ground. Always remember keeping your core warm keeps the extremities warm as well.

Got the G2s they are pretty perfect, seem to run 1/2 larger i think though so dont add a size like some of the general boot fit principles on the Sportiva site states, and there isnt a removable footbed/sock liner, but there is a fixed foamy thingy in the bed so if you wear an insert it will have to stack it on top of the fixed liner.

I climbed in the second gen Baturas (42) for years. My toes would also get cold (and bashed recently). I tried the G2SMs on at Bengate. I have a narrow, low volume foot and I felt like my foot was swimming in the G2SMs. I actually thought the Scarpa 6000s fit me better. I ended up going with the Batura 2.0s (42.5) for the fit and so far they feel warmer than the older Baturas. I also think a 6000m boot is probably more than I need. Good luck. Daniel Battin

Thanks for the info everyone.

Chris I have been to IME a bunch of times but since im a size 48 -49 its hard to find them in stock anywhere. I called the other day and they had just gotten a shipment of G2 but weren't sure of all sizes yet. May run there this weekend.

Thatcher, I wanted to get nepals but when I tried on 48 Nepal cubs they were too small and they don't go any bigger than 48. Bummer.

Ill see if they are in this weekend and then hopefully try them on. I guess Id rather have warmer feet than colder cuz I can always do the plastic bag barrier if needed for sweat.

Cheers everyone and happy climbing
(wishing there was more snow and ice in NH right now ):

I think La Sportiva makes the Nepal Extreme for the euro market and it comes in bigger sizes than 48, maybe 49 and 50? Just another option to keep in mind. Linnaeus

so another question for all you who own the G2SM

how do you feel they run for sizing? a little big, a little small, or true to size? if im gonna have to special order a pair I want to make sure they fit so I don't have to send them back for another size.

Brandonian says they run a half size large but the guys at IME in Conway said they run a half size small... Sooo what do you think
THanks everyone

I've been climbing in NH in Baruntses this year and they are warm enough to for any day in the Whites. Many days I wish for a less warm boot. They should get you just about anywhere you want to go and are much cheaper than the G2 and climb perfectly fine. Andrew Blease

Drew,

I'd say the G2SM run 1/2 size too big. I have three other la sportiva boots that fit perfectly, ordered the G2SM in the same size and I have a lot of extra room at my toes.

I've found the sizing to be pretty spot on maybe a little roomy over my other sportiva boots in the same size. i def would not size down. even though they are super light its still a big boot and imho they climb well but like a big boot climbs. overall pretty comfy and the lacing system is awesome. Total lockdown of the heel unlike the batura. def overkill for me unless the temps are well below zero. greenezo

Update.

I received my G2SM in the mail yesterday. Size 49. tried them on this morning and like a weirdo wore them to the gym to get on stairmill and treadmill with them and test them out (didn't want to mess them up outside so I can still return them in case they don't fit great).
I wore the same sock setup I would normally wear in the mountains. Thin sock liner, plastic bag for vapor barrier, medium thick smartwool sock over the bag.

Observations so far:
fit is pretty good. Seems pretty spot on for sizing. a 48 would def be too small for me (I normally wear size 14/15 hikers and running shoes). Heel has a tiny bit of movement and my toes are def at the max length. Not jammed up against the front of the boot but not a ton of extra room.
on the stairmill I didn't really notice much heel slip unless I really leaned forward and flexed onto my toes (similar to steep hiking with crampons) I also tried standing on a little tiny ledge putting as much pressure on the smallest amount of toe as possible to see how my heels felt in there. the boots did great. again a little bit of heel movement but maybe some inserts will relieve that.
on the treadmill I put it to an incline of 15 and 1.5mph while walking backwards to try and simulate hiking downhill. I did not notice any significant discomfort from my toes jamming into the front of the boot.

normal walking around and on treadmill these boots feel great. super light, not too clunky (for a big mountain boot with stiff soles).
I did notice a little bit of a pressure point on my right foot at the joint where my foot and shin come together when stepping high on the stairmill. Possibly from the boa coil. Ill have to play around a little with the inner boot and everything to make sure I keep the tension distributed evenly all around.

Played with both boa coils to see how it feels with tighter, looser tension on either coil. Very nice to be able to fine tune a bit without having to tie/ untie so much.

That being said... I def do worry about the what if factor when it comes to boa coil. I have had boa system on all of my snowboarding boots. My last pair of snowboarding boots have lasted me about 5 years and still no failure but the wire on my snowboard boots is def a bit thicker than the wire for G2's and if my board boots fail I can go to the lodge and get drunk, if my mountain boots fail it could def suck (but I can still get drunk). Im sure they took all the care needed to get strong durable materials (for $800+ list price they damn well better have!!)
And my other concern is just that pressure point on my foot joint I noticed. Only noticed it on my right foot so Maybe I just didn't have something lined up correctly or needed to play a bit.

Otherwise I think these boots are gonna be awesome. Im bummed that the New England winter has sucked this year and its going to be like 70 degrees out this weekend so I doubt Ill get a chance to test these puppies in the cold till next winter. Ill try and get up and do some technical climbing with them in the next week or 2 and then I can add more info on how they feel with crampons and such.

Thanks for everyones help in the process. I hope my review here is helpful for people.

Dude i would definitally try and challenge the plastic bags for vapor barriers, and the multiple socks and just use the 1 right pair of socks and let the boots do there job $825 double boots shouldnt need plastic bags for optimal function.. or is the vapor barrier for mountaineering boots on the treadmill odor control so they can be returned???
