La Sportiva Nuptse Mountaineering Boots - Waterproof, Insulated (For Men)

This is a full on mountaineering double-boot. Great for all season use on major peaks (think Rainier, Alaska, Canada, volcanoes in Mexico/SA) or winter work on less frigid peaks. Way overkill for what most people might climb. As other people have commented, the sizing is a bit strange. I normally wear an 8.5 (mens) which would be a 41.5 according to Sportiva. Knowing they run small and given the STP's purchase advice, I went up 1/2 size to a 42 - still too tight. My toes were right into the tips of the boot. Also, I have a narrow foot and even after going up a 1/2 size, they were still too narrow in the forefoot. Back half of the foot (heel/ankle) felt fine thought...

Haven't been out on these yet. I bought them after researching the best boots for snowboarding/splitboarding. These boots came up in discussions many times. I am planning a trip to the White Mtns. this spring and bought these boots specifically for that purpose. Will try to write a post-review when I get back for the trip.

These run really small--had to order 1.5 sizes bigger than normal. The toe box is also tight, width-wise and up and down. Once you get the sizing figured out, they are really nice boots.

I normally don't leave negative feedback but my experience trying to get a pair of these boots was bad. I typically wear a women's 7.5 (men's 6/EU 38). I ordered a 38.5(women's 8) but had to jam my feet into the boots. I exchanged them for a 40 (men's 7.5/women's 9). Even this size boot was way too small. I gave up at this point [...] to end up with no boots. There is a note on the boot description saying to order a 1/2 size larger but the note is way off and useless. [...] I have bought a lot of things here but will never order a pair of shoes from here again as one can't rely on their sizing comments, especially for this product.

Good boots 0 - 15F.
