I loooooove these boots. I use them for absolutely everything when I'm outside in the winter. These boots are very nicely made, the inside is soft and heavily insulated, are well waterproofed, are comfortable, and do a great job of keeping me warm. I can wear socks of medium thickness and I have no problems with my feet getting cold when wearing these even when it's 10 degrees outside. My feet never get cold when I wear these.I am 5'5" and 130lbs and I typically wear a size 8 shoe. I ordered a size 8.5 to accomodate heavier socks and they fit really well in the foot. However, I have a wider calf and these almost don't work for me because of that. They do have a strap on the top to adjust for calf size, but they come as wide as they go and you can only make them smaller, not bigger. They still fit me, but barely.The only other downside to these is the zipper. It doesn't work very smoothly, especially down by the ankle. When I put them on, I bend my leg way forward and that really helps getting them to zip up nicely. But for the price and for how warm they keep my feet, I am still happy with these and would still recommend them.
