I wish these shoes came in half-sizes. I tried multiple sizes on these, and thought I finally found one that fit the way Birkenstock recommends, but it turns out I have to keep sliding my foot forward to keep the arch and the toes in the right spot, or I stand on the raised bits. Basically, there's too much heal room, and tightening the ankle strap doesn't seem to help to keep my foot in place. Wide sizes would also be better, since if I go any shorter, I'll be standing on the edges.

Otherwise an excellent quality sandal, and they look fabulous.
