I also wear the diabetic socks and can attest to the comfort of them. Wal-Mart also has them in a tan color. I have gotten black and also have a blue pair from there, although I have not seen the blue color for some time. I am quite surprised there is not more of a market for these types of socks!
MrsD - you are going to start a trend here - and Mel with her knowledge - maybe a request should be put in for a forum - NeuroTalk Ebayers!
