I've only had these two days but they are a tight fit.  I've a narrow size 14 foot.  This is the first medium width boot I've ever found to be snug.  Am not able to wear thick winter socks with this boot.  I can wear thin white cotton ones that allow my foot to slide easily into the boot.  After wearing them for a day they feel narrow in the toe and ball area of my foot.  My heel slides around a bit, less so I found towards the end of the day.

My suggestion is to go to a store and try these on before you buy them.  I'm going to keep them as they are one of the few quality snow boots I've found short of my Vasque Sundowner hiking boots.  These are still better for slipping on and chasing down rover when he gets loose in the winter.  By the time I've laced my Vasques hes long gone!

I'll review more after the snow hits and I try these out on snow shoveling and walking about on icey driveways and sidewalks...best of luck!
