Been wearing this baby for going on 18 weeks now.
YES, I said 18
WEEKS! 
I broke my ankle back in July and wound up having surgery in October. Actually, of all the splints, bandages, etc we've tried, the walking cast has been the most comfortable for me.
I like it because you can take it off for a shower and if I'm a good girl and don't get up I can take it off and lay on the sofa and let my foot breathe

Usually they have inflatable cushions built in so you can adjust the tension to your own needs which tend to change a LOT! I went out and bought some of those
BIG STRETCHY FUZZY socks you wear with jammies, you know the kind I mean? I wear 1 on my bad foot and it stays warm and provides extra padding and prevents irritation and it's not too tight which I found was a
HUGE problem with regular socks.
Sorry to see you join the Gimper's Club. It really sucks
