Great fit. Very comfortable and the previous shoes I wore on 10-hour shifts left my heels sore - not these! Had one slight problem with the top of the boots digging in above my ankle in the first week, but this was resolved by loosening the lacing.
I am presently breaking them in little at a time but they do work. I usually wear trainers for walking but they are cold. The boots do help keep me warmer. Since my feet are great is reason breaking them in little at a time.
