Sockology is the branch of sartorial science that tries to explain why some socks are deemed a bit odd. Why is this so? What makes them different? And why are people afraid of them? The answer probably has much to do with their constantly varying pattern of behaviour. You’re never quite sure what you're going to get and for those who like everything to be exactly the same all the time this can be a little frightening. But for everyone else, it's what makes life worth living.
