To celebrate the 2026 Chicago Marathon, we created a limited-edition sock inspired by the city's reflections at every mile: distorted, unexpected, and always moving. This design is a commemorative piece that honors the course from Grant Park and back again. As a finishing touch, CHICAGO runs across the front, for every mile ahead.
