The insides are so soft and warm!  I have uggs as well and these are far more warm and unlike with my uggs I get tons of compliments on them. The soles have great traction and don't feel like you're walking in slippers. I already wore them in 30 degree windy weather and they were awesome. I normally wear an 8 1/2 in shoes and got these in a 9 so they are a little loose but I do wear socks so that helps.
