My dad is now into his third year and remains cancer-free after surgery, radiation and chemo for pancreatic cancer.  It hasn't been an easy road.  Truthfully, the chemo nearly killed him.  He is slowly regaining his strength and spends 90% plus of his days inside the house.  The last thing he needs to do is slip and fall.  These wool slipper socks were bought with that in mind and are proving themselves to be his first line of defense against just that.  The small tacky dots on the walking surface grip better than anything I've yet seen.  He loves them.  The wool socks are also thick and very well made, keeping his feet nice and warm.  I highly recommend them for anyone, including diabetics, who spend many days around the house, hospital, nursing homes, etc. where they are seldom in shoes.  In fact, he refuses to wear any of his slippers anymore.  These wool slipper socks are the best purchases I've made in a long time.  No regrets.
