I typically wear 8.5 in sandals and need 9 in athletic shoes and boots. These were only available in a 9, but I ordered them anyway. Good thing! I have an older Gustar style pair of Franco Sarto sandals size 8.5 and they fit perfect.
I put this pair of Grip2 size 9 sole to sole with my old 8.5 pair and they are the exact same size.
Otherwise they are extremely comfortable considering they are so minimalist. I wore them for the first time all day to a 4th of July cookout with no discomfort.
I didn't notice from the photo, but the denim is very lightly glittered. Im not a glitter person, but it didn't bother me enough to send them back.
