These boots are very warm and cozy. We purchased them last year and were so impressed with the style and workmanship that we purchased them again in the next size up.  They run True to Size and can be worn with thin or thick socks without getting sweaty toes.  The price is great and they last until you need to hand them down to the next kid--much better priced than other pricey brands.  Definitely recommend these to all who have the need to keep little tootsies warm in the winter ;)
