"I usually wear an 8 1/2 in most shoes, however with Mule or Open-Back Sandals I always bump-up to a Size 9, so my heel doesn't hang out the back or the toes don't run over the front of the sandal. BTW, I have long, slender, narrow feet. This VaVoom Sandal is so pretty with the subtle bling on the front, its a soft patent leather white look, not too shiny & may I add that it's hard to find pretty white sandals in for the summer. This Vavoom does all that & is very comfortable. I will probably get this shoe in the beige as well."
