Playmakers (Okemos, MI)
This running store occupies a former Barnes and Noble, but it's not the size of the shop that makes Playmakers a beacon for athletes, but the community involvement and education. Playmakers sponsors an elite racing squad, but also offers teams and training programs for all ability levels and goals. The store also puts on free weekly injury clinics, runs a local foundation to improve community health, and partners on more than 100 races every year.
