When Alan and I went to our neuropathy support group meeting the other night, they gave out free Foot Huggers socks for us to try.
You couldn't tear these away from me if you paid me.
I have a ceramic tile floor (that's always cold). I put on these socks and I never felt the floor.
So go and poke around and see if you want to get yourself some of these.
