I don't know why everyone loves these shoes, like Jennifer Aniston. For one thing, the size guide is wrong. I'm a US 7 1/2-8. I got the 38 and it was a boat on my foot. I ordered the 37, which is supposed to be a US 6 1/2. (No way would I be able to fit my foot in a 6 1/2.) It fit okay but it was very wide. These are platypus shoes, and very stiff. I don't see them being comfortable. I returned them. Maybe the company should stop making them unisex.
