I know many women love these shoes but I found them wide and I have a wide foot.  I am difficult to fit due to various foot issues. The arch would poke into my arch and I think it would take a very long time, if ever for me to get use to these.  Like walking on an extremely firm foot bed.  Tons of toe room.  I couldn't tighten the strap tight enough to ensure they would flip off my foot.  Their flip flops where you toes have something to grip may be better.  The toe bar on me was not placed under the base of my toes as it should be.  I could feel it with the tips of my toes.  I think I will give their orthodic a try instead of their shoes.  They were pretty cute and appeared to be made well.  If you have a wide foot their medium is more like a wide.  The heel cup was very deep and I can see how it would properly control your ankle motion.
