Amazing product!
I read a lot of reviews advising UK to size up, I think this is required if you are a half size. For me I’m a 7 uk and I purchased men 8, when they first came they were tight but they do break in really well and they aren’t too big but they aren’t tight any more, they are comfortable but I also got myself a men 7 and they fit a bit more snug once being broken in. I tend to wear the 7 outdoor and the 8 indoor
