This boot is quite comfortable - and warm!  Seems well made.

I wish the shaft though was a little bit wider,like the Eva boot -
=>They are a bit tight, but not an uncomfortable tight - If you have skinny calves you should not have an issue with that - but I cycle and my calves are not skinny.

=>I wear a size 6, ordered a 6 - at first a bit tight at the toes, but broke them in with big socks and now no issues with that.

=>As I read another reviewer - the shaft height is indeed 10.5" not 10" which is very okay with me.

Overall am pleased - would have given 5 stars it the shaft was a bit wider - but I think if you have thinner calves, this may not be of any issue.
