I bought the black pair in my normal women's size 7.5 (euro 39), and in an 8 just in case. (Yes, you will get a low pair of black boots if you select black, you won't get the taller blue pair).

I didn't even bother trying on the 8 because the 7.5 is borderline too big for me. If I wear really thick socks with them it'll be fine, but if I wear them on a rainy summer day I may not necessarily want thick socks on. Also the rubber seems a little more thin than it should be. The size 7.5 came slightly dirty and in an unmarked box, but the 8 is clean and in original box so not sure what that's all about. I'm slightly worried that the rubber would rip easily.

I got them for a good price so I might keep them because they still are cute after all. They're posh looking, I was drawn to these after I learned that Kate Middleton wears them. If the price of them were any higher it would be a rip off.
