I bought these a few months ago so I've had the chance to wear them in.
-They fit over my calves and slide on easily.
-They are very comfortable
-I can wear them with almost everything
-They run slightly large, I even put in inserts and my feet are still moving around.  Not a deal breaker: if they were fit and snug, you'd be able to see your toes bulging from them.
-They do change color with snow/water but it dries and it doesn't stain.
-They do look of slight poor quality because of the color.

I definitely recommend these boots, they are very cute!
