We moved to Anchorage Alaska this past fall and wanted to make sure my 3.5 year old was able to get out in the elements. Didn't like spending this much on a boot for a child that age considering how fast they grow but did it anyway. These are the greatest. They are easy on and easy off. They handle the coldest and wettest temps. Her pre-school goes out for "recess" up to -15 degrees Fahrenheit and she loves it. Never gets cold feet and loves the style of her boots (future fashionista). Lifesaver for parents who need to get the kids outside during the winter for sanity reasons. We liked them so much we already bought the next size up for next year.
