I love the boot. It is warm inside the house as well as outside when I dash out....live in Wisconsin...great boot. Little tight getting into the boot first thing in the morning because the elastic sides are still tight, but using a shoe horn does the trick and then it is nothing but comfort and warmth...the size also accommodates thick wool socks...if anyone is planning to wear heavy socks with these boots then she should be sure to order a size which will allow that.
