I love these socks. I originally found them at Sam's Club and loved them so much I went online to find more and well, here I am.
They are thin in the right places and thick in the perfect places. I think these are the only ankle socks that I've ever had that don't need to be constantly fixed from sliding off the heel. They have a little silicone grip that keeps them in place but luckily it's not noticable. I think what I love the most is that there is no elastic band at the instep, its flat, so it leaves very minimal indent marks on your feet.
I've literally thrown out all other ankle socks and stocked up on these. They're great!
