Marathon Sports is a local chain with several Boston-area locations. My favorite is the one on Boylston Street- located at the exact painted finish line of the Boston marathon. It's very symbolic, and could give runners the extra motivation they need to purchase new shoes, clothes, etc to make themselves better able to finish the races in their future. This store has everything for runners and joggers- from sneakers, pants, jackets, shorts, outfits and accesories. This is one stop athletic shopping at it's best. The staff is knowledgable and will help customers outfit themselves appropriately.
