Toss out those ratty old socks that you’ve been unsuccessfully rotating and upgrade to this chipper collaboration from Giles Deacon and Happy Socks. The limited-edition run (only 1000 sets made) has a different pair for each day of the week, so you can stay fresh daily. And do buy all five, too, because the Elton John AIDS Foundation will receive 25% of the retail price of each pair to further their work with those living with, affected by or at risk of HIV/AIDS.
