Quality, warmth and style
Size: 13 Women/12 Men, Color: Black
Bought these for my husband and he loves them. True to size and keep feet warm in the WNY winter weather. They are a great boot due to durability and ability to slip on and off.

Size runs wear!
Size: 6 Women/5 Men, Color: Black
The ankle area is super tight so it’s hard to put them on and harder to take them off. They run big because I wear a size 6 and these fit like a half size bigger. Returning them!
