Time Out says
Not sure if you’ve noticed, but Boston takes its running pretty seriously. Marathoners and recreational joggers alike flock to this running store (victoriously located at the Boston Marathon finish line in Copley Square), where associates let you test-run different shoe styles for fit. Snag some socks and some insoles, and you’re off to the races.
