I bought a pair of these tube socks to use for my Jack Nicholson Joker Halloween costume.  They stay up all day and night and won't fall down.  They are very long socks that go all the way up to my kneecaps.  They are tube socks if there ever were tube socks.  They are made of 80% hi-bulk acrylic and 20% stretch nylon.  The adult size range is 9-15.  I highly recommend them.
