I wore these for the first time the other day when it was snowing here.  They are so cute and adorable.
They fit well and feel very comfortable.  I usually wear a size 6 to 6.5.  I ordered a size 6 and they fit perfect and there is room for socks.  I would recommend wearing knee socks with them, or they will rub your leg if you wear them under your pant leg.
The color isn't as vibrant as the picture shows but that is perfectly fine with me.
