i was scared to buy these because they did not come in half sizes. i bought a size up as recommended and naturally they are too big...not too big that i should have purchased a size down...but big enough that it is annoying and i occassionally slip out of them. it probably doesn't help that i have a narrow heel, but regardless...if they had half sizes they would have fit perfectly. still, a shocking, eye catching, yet sexy shoe that i can definitely see myself wearing all the time.
