FWIW, If you have feet issues and tend to get blisters easy, try wearing a thin LINER sock.
A friend who runs those off-road marathons turned me on to another little trick too.

Before the liner sock, rub you heels, bottom of foot/between toes etc with a good SLICK feeling deodorant. Between that and the liner sock it cuts way down on friction that causes feet issues.

This won't work obviously if there is a material defect in the shoe but its a good trick to use when your doing something that is hard on your feet.  ;)
