Wedges tend to be more supportive and these hold true to that.  As far as fitting goes, I am a true 8.5 and ordered them in that size and they fit very well.  I got them in white and they look amazing.  I like these because they're sexy but still cute enough to wear to church (at least the white ones) (and not that I go to church but maybe you do) with a knee length skirt.  For 15 dollars, its totally worth the money!  I love shoes and can afford my shoe fetish thanks to good deals on GREAT shoes like these.  :)
