I got a pair of Scarpa Mont Blanc's for a trip up Rainier next month as well as ice climbing. I normally where a size 7, but when I tried on the 38's they felt cavernous. The store didn't have the 37.5 in stock, so just for kicks I tried on the 37s. They actually fit really well! Especially with some SuperFeet in them to prevent elongation and mostly to support my arches. They felt like they were an extension of my foot, almost the way my alpine boots feel, though not quite as tight.
Here's the rub: when walking downhill (toes pointed straight down the sloop) on the little ramp in the shop, my toes, mostly only in the left foot, crash into the tow box. Not anything painful, but noticeable. My fear is that it may be tolerable for a few steps in the store, but could become more painful with thousands of steps down a mountain. No beuno.
However, 90% of their usage will be for vertical ice climbing in the East which there is no problem with, even when trying to aggressive kick the toes like when front pointing.
I don't mind a few black toenails, but if I end up in excruiating pain and can't walk down a mountain, that could be a really dangerous (and dumb situation).
So, do I swap them for a pair of 37.5s to be safe, or am I over thinking this? I tired them on with my winter socks, on a super hot day, so I'm thinking there's a chance that they will have more room with a lighter weight sock (for an August Rainier ascent) and when it's cold and the tissue contracts a bit more.
How do you prefer your boots to fit?
