The size was exactly right for my shoe sizes.  These boots are heavy when you pick them up, but on your feet they're very comfortable.  The support is EXCELLENT.  I've had them for almost a year and they're as good as new.  Highly recommended.  PS put in one of those arch support cushions and they fit even better!

As a project manager, I use these boots only two to three times a week when I'm on job sites, so I'm not exactly beating them up, but I would easily recommend them for more strenuous use.
