I am using these as a way to protect my feet when I split wood.  I do not use them every day, but may be in them for several days in a row for multiple hours a day.  They are comfortable and sized right, if not a little wider than a normal medium width.  My only complaint I have is the weigh a lot, but I'm not running a marathon in them, so this is not a deal killer for me.  If the extra weight means extra protection, then I'm completely satisfied.
