A bit of ghetto athletic - a definite youth sock.
School disco from the knees down.
Blue on blue - the slight tonal variation between shoe and sock is a clear winner. Socking great and helps to avoids confusion when getting dressed in a tent for five days running - win/win!
Festival favourite..... colourful, strong pattern without being garish = a top sock.
An apparent sock accident - this fellow could have done with a little help from blue on blue.
