I usually wear an 8.5 but my toes are at the very end.  I'm considering returning them but I got such a good deal I may try to stretch them; plus there are no size 9's in stock :(  Other than the sizing I love the shoe.  I have high arches so I have a real hard time wearing 'flats'.  These have just enough of a heel to make them not completely flat.  They also have very nice padding.
