I wish I could tell you some amazing things but alas the insoles I was sent are small, I have size 11 feet and these might fit a size 6 or 7
what I do like is you can easily feel the piece for the ball of your foot and for the arch, even a sweet heart for your heels but.....if I was to put these in my shoes they would be useless as they are way too small for me
if you want to see them for yourself, check it out here
