Foot size
While they seem well thought out and well made, when the product arrived the paperwork with it said that these high arch supports fit Men's size 7-11.  I have size 13+ feet.  Tried them anyway, but they basically disappeared. Helped a little but not enough.  Tried doubling on one foot both fore and aft and one on top of the other.  Too much support.  Hopefully the company will be successful enough to branch out into the fringes of foot size.
