Purchased a pair of gray Cardy for my 19 year old daughter for Christmas.  She loves them and seems to NEVER take them off.  I always swore I would never wear Ugg boots.  I am 45 and thought they were kind of trendy looking for the teen set.  Well, I tried my daughters on and WOW.  It is like wearing the warmest, most comfortable slippers in the world.  I just purchased a pair of black AND a pair of tan Ugg classics for myself.  I may never wear "normal" shoes again!!!  **Remember to size down as Uggs do run large.
