I now have 14-15 pairs of Alpha sox. I had to let my roommate have a pair to try, he loved them. We are 76 and he’s 77. Walks a mile every day. I’d recommend anyone to try these. The only thing- the white ones , I ordered 3, are almost too tight. Not sure why they are tighter than the black ones. They cut into my ankle, and around my knee. Maybe I should have ordered a size larger. ?
