Well, as usual, Kitty and mrsD are both right.

I have worn the socks for a week now, every day ... and yes, we washed them.
They are very comfortable and my feet are not sweating. So they apparently DO wick the moisture away.

My cotton socks will get a rest. I plan on buying some more. I have not worn any of their other products, but will try them if I can get them for a good price.

Thanks again...Dave
