If there is anything that must have, it is comfortable shoes. I was never a slipper man, but decided this was the time to get a pair. Wow am I not sorry! These have been the most comfortable and warm slippers and I never want to take them off. I just might be wearing them forever. My feet were dry and cracking, no matter what creams I used as a softener, since wearing these slippers the problem has magically gone away. I don't usually write comments of recommendation unless I find an unusual product, these (shoes-slippers) deserve accolades.
