I got tired of boots that allowed snow to get into my childs feet and snow play was interrupted by the hollers of "I got snow in my boots!". Since I purchased these and my daughter has been wearing them (2 winters now), no complaint! She loves them and so far they have kept her feet dry, warm, and comfortable. The drawstring helps keep the snow out and warmth in. I purchased a size bigger to allow for thicker socks and extra wear. But rarely does my daughter want to wear thick socks and they were still warm and comfortable. The wool liner inside is very thick, so it must do the trick. The liner in removeable. These make great rain boots as well since the rubber extends up over the ankle. Good quality versatile boot!
