Great boot for cold winter ice climbing.
I bought this boot for ice climbing in New Hampshire. I've been out four times now in temps down to the single digits (F). Finnish: The first thing you notice when unboxing these is, well, how nice looking they are. The "look" like the build quality is exceptional. Weight: Size 43 (US 10) each boot weighs exactly 1000g. Fit: The fit right out of the box is fantastic. The sizing seems to be spot on with all my other shoes. (US 10, EUR 43). My feet are a little wider than average and I often have compression at the widest part of my foot. Not with these, these fit perfect. I'm not sure how these will fit a narrow foot so be advised to check that if your feet are narrow. As mentioned in other reviews, the lacing system is simple and functional. The locking eyelets allow differential tightening between the top and lower part of the boot. Crampon fit: Grivel Rambo 4 crampons fit perfectly. Steep ice. Great support on steep ice. Hiking: The stiff insole that make these great for vertical ice makes these relatively stiff and inflexible for hiking. For approaches on snow they are fine but I'd look for something else for longer hikes that don't involve steep climbing. Warmth: My feet get cold. I have some toe nerve damage from many years of playing outside in the winter. I have used these standing on ice for 6 hours in air temps in the teens. I've done a couple hikes in temps in the single digits. I do have to put a chemical toe warmer in the toe of the boot but with that my feet have been comfortable in those conditions. The G5 Evo's are probably warmer but these work for what I want. I am very impressed and happy with these boots for what I need (winter ice climbing in temps down to low teens (F). I recommend these for this purpose and would buy again.
Weather Proof
The quality doesn't disappoint. They feel comfortable and warm. Sizing is mostly accurate when one leaves thinks of extra space for thick socks and crampons. The inner sole has an arch that may feel awkward until one gets used to it. Lacing is complex as provided laces are short. Bots this heavy require double knots to firmly keep the laces tight. Leather is beautiful and I enjoy the colours. Overall, an excellent warm alpine boot. My last Sportivas lasted 10 years of heavy use and abuse.
First Impressions
Have half a season in these and the impression so far is very positive. The boots are comfortable, no issues with breaking them in, no awkward spots or pressure anywhere. The lacing system let's you dial in fit. Having the little rings lock of the lower half of the boot is quite nice and as long as you double knot the upper section stay tight as well. At lower temps (lower teens) I started to feel a bit cold, especially when belaying, but this is manageable with a double sock or just something thicker. One area which I think could be improved is the amount of space on the crampon lip, it could be a bit deeper. In deeper powder this did not disappoint, absolutely no snow got inside. For sizing I went with a 44 (I'm typically a US 10 in street shoes), and that gave ample room for the foot to move when using crampons without feeling loose in the heel.
