I always am a size 8 in Sam Edelman shoes/boots/sandals etc. The 8 in these were so small, and uncomfortable I had to return. The opening to the ankle is really skinny, and the rubber is hard and poor quality so there's no give to stretch the opening of the boot. Then once you've wrestled your foot into the boot, the fit is so narrow (again due to the hard/poor quality rubber) and tight it's uncomfortable. If you're going to order these,SIZE UP!
