To celebrate the 130th running of the Boston Marathon, we created a limited-edition sock to mark the world's oldest annual marathon. This vintage-inspired design is a commemorative piece that honors the heritage of the race with a playful twist. As a finishing touch, we've included a note of encouragement on the inside cuff, for every mile ahead.
