New Sportiva "G-Tech" Ice Boots?

should probably get its own thread eventually- but here’s a trade show preview of the ‘g summit’ that someone mentioned.
Looks like it has a ‘thin removable liner’ approach. I’m a bit skeptical how much it would change the fit to wear it with/without as he suggests, or how much warmth it actually provides..

I beleive the ommision here is that it either has a spacer mesh liner or a foam liner, making it suitable for summer or winter alpinism. Maybe it's a "high altitude" boot for summer in Nepal moving fast but I'm skeptical of its use as a "high altitude" boot for normal people. 

Over at Climb On Equipment (in Squamish, BC, Canada) we just got the G Tech in. As a semi-obsessed ice climber, I have to say it is pretty impressive! We made a short video overview of the boot you can watch here: https://youtu.be/n_qEwGujtXw 

I have had the g-techs for a few days now in 3 sizes. They fit my feet better than previous LS boots. However I have some durability concerns and one of the pairs has a pretty substantial manufacturing defect. They are light and walk WAY better than my phantom techs. My feet actually roll heal to toe instead of clopping down like the phantom techs.

I'm surprised that you can fit in both Phantom Techs and G-techs.  Generally, if you fit Sportiva, you're not going to fit in Scarpa, and visa-versa.  

I fit well in Scarpa boots.  Other than the Spantik, I've never been comfortable in Sportiva boots.

I wear both brands fairly interchangeably. I have G2SM and Aequilibrium Top from Sportiva, and Phantom Tech, Ribelle Tech, and Phantom 6000 HD from Scarpa. All of them seem to fit me well. Sportiva is notably tighter in width through my mid-foot but not uncomfortably.

I have a wide, high volume foot shape.  Sounds like your foot is more "normal."

Slightly wide, very low volume. I have small ankles and relatively large calves. It's made life hell for finding ski boots but climbing boots seem to favor me a little bit more. I'm much less happy in the more "anglo" climbing brands like Mammut, Zamberlan, etc.

Have a bit over a dozen pitches on mine, so far, and i like them quite a bit. The only gripe I have with them is the durability of the lugs--I've already had small chunks shear off on rockier snow covered approaches. They climb very well and the lightness is noticeable. 

I came back here to say the same thing. I have been using them quite a bit and love how they climb but don’t like the tread as much as my old Nepals. They don’t seem as durable or as grippy on snow covered rock 

Hi Guys,  I’m planning to go To Denali would this G-Tech be enough quality and warm for this expedition. Or do you have other options.
thanks

No. Not if you wanna come back with toes. I have a buddy climbed last week in G Techs in New England on a “high teens” day and had cold feet.

Definitely not. You’ll probably want double boots. These are less warm than nepal cubes which wouldn’t be a good choice themselves. 

Hi all, how do you feel about the sizing of the G-tech compared to other Sportiva boots? I have the Spantik in 45.5 but then I tried the Nepal Evo yesterday (only one I could get my hands on in the NYC area) and it's more on the 44.5 side. Now I guess if anything the G-tech would be sized more like the Nepal then the Spantik. What is your experience? I had the old brown Nepal classic in 45 I believe 10 years ago, so I was a bit surprised about the Evo sizing. Thanks all!

I have the same size of G-tech as my Nepal Cube GTX 

Anyone have tried them? how about waterproof performance

I'm a 45.5 (w/ volume reducing tongue insert thing) in the Nepal and a 45 in the g-tech.  

I'd also add that these are noticeably warmer than the phantom techs - not night and day, but warmer w/o a doubt.

I am selling a pair of G techs in 42, too big for me after a couple days out with them. Good condition, small nick on the rear rand, message for pics 

Size wise: I have the same size in TX3s, TX4s, and G-Techs. I could maybe go a half size up in G-techs but they seem fine as is.

One thing to note is that I did have the Boa dial pop off while just casually walking through the woods recently. It's pretty easy to reattach if you know how (press it back in and twist the opposite direction as tightening the boa laces. You should hear/feel it pop back into place) but was definitely a bit of an annoyance.

Overall feel like they're pretty waterproof. Been walking around in ankle deep snow in them a decent amount (like, probably 10-20 miles so far) and haven't gotten wet at all. I'm likely going to try them on a little stream crossing friday and will update if my feet get wet from that. These are my first pair of boots so I don't have much to compare them to, but they maneuver around pretty well. Haven't had a chance to actually ice climb in them yet due to a shoulder injury but they do the non-climbing part better than I expected.

Anyone have any idea when more sizes will be available?  

I  was told in an email, not till fall...I will be at Ouray Ice fest next week and know some folks, I will try to find out if that is true.
