I'm giving these boots 5 stars as they are the only boots I have ever had that actually warm my feet up. I have permanently cold feet every winter and have to heat shoes/boots with a hairdryer before putting them on. These I put on the first day (in snow) not having warmed them and by the end of walking the dog my feet were lovely and warm. They are fully waterproof ( I waded through snow) and extremely comfortable. I am size 6 and bought a size 6 and they are a perfect fit. They are stylish, elegant, cosy, comfy, and very very warm, and true to size.
