Too narrow

Great quality boot, I just wish the toebox wasn't so narrow.

Lightest 3 season boot EVER!

I've used it several times
Size Bought:
39 1/3
5' 6"

I've had these boots for about 3 years now. I mostly use them for alpine climbing and scrambling with snowy/crampon approaches. These are the PERFECT boot for the Bugaboos or something similar. They are light enough you don't mind wearing them on the long hike with a massive bag to get up to Applebee campsite. I find they climb and edge really well on 4th/5th class terrain. The real winning aspect of these boots is they are so incredibly light. I am a 7.5 US women and I wear a 39 1/3, I would describe it as a performance fit but I actually have been enjoying that and haven't had any issues yet.
