We love endorphins, the happy brain chemicals that activate in response to exercise, blocking pain and giving us that “runner's high” we're always chasing. These funny running socks are perfect for athletes with a cartwheeling stick figure and the words “Endorphins! Fuck yeah!” Wear a pair on your next trip to the gym to remind yourself why you go the extra mile on the treadmill: because of those sweet, sweet endorphins, baby!
