I usually order a size 6 in pumps. This 6 was just a bit loose which caused blisters. It's likely because it's a sandal and not a pump. They are difficult to get on and off, not easy to slip into, therefore I wouldnt order a half size smaller if given the chance - I don't think I'd be able to get them on otherwise. I put blister covers on my feet the next time I wore them and they were just fine.

IMO the shoe is very stylish, fairly comfortable for the heel height. I only buy heels over 3.5" if there is a platform and these were no exception. Overall I'm very happy with my purchase.
