Perfect
Highly recommend. I have hiked hundred of miles in this boots by now. Through alpine environments, water, slick rocks, scree, etc. I've scaled in these. I have yet to try them with crampons. Personally, I tried 3 sizes. My normal shoe is 7.5-8 US. I tried 7.5 first, then 8 and then 8.5. Sizing up 1 size was best for me. I tried 1 half size up I find that after walking for several days multi hour days my feet swell and the boots feel tight and I can't wear thicker or padded wool socks if the shoes are too small. While they are comfortable out of the box, walking all day for multiple days on end on hard rocks does eventually cause pressure points that socks with appropriate thickness and padding can fix, but I can't wear thicker socks if I don't size up.
