If you have ten identical socks how can you differentiate between them? If you wear sock 2 and 7, which are still an identical pair, how would you tell they weren't a matched pair? And why would you care anyway? You'd be wearing a 'pair of socks' that match.
Socks come in left and right forms, so it is important to match them up properly.
