Calvin Klein Men's Pure Cotton Rib Socks - 6 Pack Comfortable Athletic Crew Socks for Running, Gym & Everyday Wear

Bought these for my boyfriend who wears a size 11 shoe. They are nice cozy socks, but the heel of the sock ends up on the back of his ankle. Way too big, which is surprising because his foot size is on the larger end of the size range listed. He still wears them, but I think its only because he feels bad if he doesnt since I paid this much for one pair of socks.
