I purchased these boots about two month ago, but am only wearing them for about two an a half weeks. It snowed already, and like promised, you can really walk in the boots careless and happy, since you don't feel any kind of cold or wetness crawling through, and I am walking quite a bit - about an hour a day at least.

Update - (more than 4 years later) - I LOVE THOSE BOOTS!!
It is important to say that I moved away from the Midwest,so have only been using them heavily for the first two years. Now I am in NY, so am only using them rarely. However, they are a pleasure to ware, comfortable, warm, dry, (and ugly as only snow boots can be..;-)).
I warmly recommend them!!
