UGG Mouton Boots Black Size 8 (25cm) Overall, there are signs of wear such as scuffs, fading, and wrinkles, but there are no problems with the cold protection. I think you can still use them. How about for cold protection or work? The boa inside has a good thickness and resilience in the shaft and is fluffy, but the footbed is worn. The outer side of the sole is worn down.
