I have bought Sporto boots in the past and love the quality. I bought these boots after much online and in store searching. I wanted waterproof boots with thinsulate lining. I live in New England and our winters are very cold and snowy. I have worn them a couple of times so far walking in deep snow, and no issues with warmth or water getting in. These boots are also very cute. I bought 1/2 size up based on other reviews. The size is good with thick boot socks, but the zipper is tight on my calf. I don't have a problem generally, so not sure what to make of it. I decided to keep the boots based upon price and it is late in the season. I wore the boots all day shopping and they were very comfortable despite the snug zipper on my calf. I am very happy with these boots so far.
