These are some of the best no-show socks I have bought.

They fit well (tight, I have a 12 foot) but comfortable.
They do not slide down (back ankle area) like a lot of my no-shows in different shoes while walking.

OK after a few washes - did not shrink much.  I am ordering a 12 - 14 to see difference - will note differences.

I recommend these highly!  Now my favorites.
