"Believing other reviews and the product description, purchased the ruby propet blizzard snow boot. I ordered a 1/2 size up in case I needed the extra room for thick socks. Thankful that I followed this instinct it is an exact fit with the 1/2 size up. I put them on when it was the first snowfall and my feet felt cold. I couldn't tell if water had leaked in or not. Further the flap of the boot is not sewn to at least past the ankles as a lot of other winter boots are. They look cute with skinny jeans and as long as I have my other ugly waterproof winter boots to shovel snow in, then they are kind of worth it... if nothing else for the color. I didn't have to break them in which was another plus."
