I can't offer any more advice to the already good responses, but wanted to pass along some info I just read from a podiatrist. He said that UGG's are bad for your feet. Because they have no arch support, they can cause heel spurs. He recommended slipping in an arch support to help, but that kind of defeats the purpose of why most wear them. Also, because they are so warm, many people wear them without socks. This can lead to fungus growth because of the length of time they are worn, unlike slippers. I'm not a fan of UGG boots, but I really like the UGG Tasman, more of a slip on.
