These boots are very pretty and worm too. I wanted to get them to walk my dog on rainy days. So, based on other peoples reviews, I got the size up - they don't have half sizes. I usually wear 8, so I ordered 9. They were HUGE! I returned them, and ordered 8, it's European 39 (according to the manufacturers site). These are a little tight. I can feel the end of the shoe with my toes, and the upper part of the shoe presses my feet. I kept them on for three hours, trying to understand if I can keep them and after that took a walk with my dog. Well, walking in them is a real pleasure, very soft, very warm and not slippery at all! I think I will keep them, even though I would prefer if they were half size bigger.

No. I will return them. It's annoying to feel the end of the shoe with my toes, I know it will eventually hurt.
So, if you wear half size and order up, it may work for you just fine. But if you wear whole size, it may not be the shoe for you.
It's a shame, I really wanted the boots to work for me.
