I first bought the green pair in a size 8. I love them and the color. They are a tiny bit big and I tripped and scuffed the toe either the 1st or second time I worse them. I decided to order the silver pair in a size 7. The silver is a shiny, glittery look, which is fine. The size 7 is almost too small, but wearable. I wore them all day and by the end of the day, the straps had left marks across the top of my feet.  I wear anywhere between a 7 to 8 in shoes and I definitely should stick with an 8 in these. The blue and red pair are the next ones on my wish list. I get tons of compliments from both pairs of the green and silver. I would definitely buy again.
