It's a great boot, don't get me wrong, but I'm not sure if it's worth the money. I wore mine on my Elbrus summit, and it felt comfortable. They are wide enough and fit super. I wore them with nothing but an insole as well as with the inner liner for extra warmth when needed. Apparently this boot should be ok when worn with a liner, in temps even up to -30 C. However, at some -15°C, I felt small discomfort and cold, but it went away with time. When worn in deep snow but with temps around zero, my feet started sweating, and the boot was wet inside. It dried rather fast in the sun, so that is a good side. After several days of usage, some lines caused by crampons started to appear, which I find unacceptable for this price range. It's very easy to pierce the boot with crampons, and all the La Sportiva markings have already started to peel off. For this price, rather low quality.

Hi Michael, we're based in Germany but can ship to R.o.I :-)
I can not understand from the description of the shoes are sold with or without a boot? it is not visible in the photo
Hi Alexandr,
"Thanks to its special, removable inner lining, the G-Summit can be adapted to the thermal requirements of the terrain and the operating environment."

Hi, climbing Mera Peak next year, followed by a 7000m expedition. Are these boots suitable for both climbs, and are they also appropriate for technical mountaineering?
Also, could you let me know when you're expecting more sizes back in stock?
Hello Peter,
I think the boots are suitable for the Mera Peak. For the 7000m expedition, the boot may reach its limits, so a La Sportiva Olympus Mons Cube or the Scarpa Phantom 8000 would be a better choice. For detailed advice, you are welcome to write to us at [email protected].
I have not yet been able to see any repeat orders in the system. Unfortunately, I can't say at the moment when something will come back into the shop.
Best regards
Paul
Temperature cover range
I am aware that this is a hard question to answer, but what could I expect from this boot concerning its warmth? I don't get easily cold, and if worn on good Merino socks, could this boot be warm enough at -30C or -40C?
My intention is to use it mostly for winter EU mountains (such as Elbrus or Mont Blanc) and potentialy Aconcagua and Denali. Prety much, for everything around 6000 m!
Hi Aleksandra,
No temperature range or specific altitude is offered by La Sportiva, they only state the following:
The new benchmark for high altitude technical mountaineering. Ideal for ice climbing and climbing big walls, technical treks in winter conditions and staying in extreme places at low temperatures. G-Summit was developed with the aim of satisfying a double need: an extremely thermal product for high altitude mountaineering and a surprisingly light and precise double boot for expeditions in highly challenging climates. In fact, thanks to the special removable liner, G-Summit turns is a customisable product based on the thermal requirements of the terrain and environment of use.
I would however , say these should suit your needs perfectly.
What is the relative sizing of these compared for example with the Aequilibrium ST GTX ? In specific my Aequilibrium ST GTX are a size of 47,5 and i am happy with them, would i go with the same size in the G-Summits or should i size up in order to account for the inner liners?
Hi sokratis,
I would expect that size EU 47.5 in the G-Summit should suit you well also.
I'm aiming for Ama Dablam in 2025 and I'm still undecided which boot I shall invest in. At the moment I'm between the G-Summit or the G2 Evo. I'm looking for a lightweight fit with enough insulation for a peak of over 6000m, and comfort to tackle the technical rocky and icy faces. Your advice is greatly appreciated.
Dario
Hi Dario,
For a peak of almost 7,000m you will be better off with a more insulated boot and either the La Sportiva Olympus Mons Cube or the Scarpa Phantom 8000.
Thank you for the suggestion. I'm afraid the Olympus Mons and Phantom 8000 may be too heavy and bulky for this particular climb, but are suitable and warm enough. I'm still unsure, but I appreciate your advice :)
