I'm a 9.5 in womens and the website said to order a size bigger if you're a half size. So I ordered a 10. They technically fit, but there's quite a bit of wiggle room. A store started selling these after I bought them online, so I decided to try the size 9s. They fit much better.

The shoe works fine, but the cut is below the ankle, and water always ends up on my ankle/socks there. They also don't breathe very well, but that's what all rubber shoes are like. Cute design, but everyone thinks the goats are dogs. But that's no big deal.
