These boots have worked out well for our snow season this year, but I agree with other reviewers that they run quite small.  I bought up one size for my daughter, and the wool inserts were still absurdly small -- they didn't fit her feet even without socks.  So we put her in socks and just the rubber outer boots, skipping the inserts, and she seemed to do quite well in the 18" snow drifts.  Her feet stayed warm and dry each time we went out.  So, the boots alone work well, but it's too bad we couldn't take advantage of the inserts considering how much these cost.
