At Niketown, 669 N Michigan Ave, at Erie; Magnificent Mile; 800.806.6453
In celebration of the brave souls who will be trekking 26.2 this weekend, the folks at Nike rolled out a custom Chi version of their LunarGlide+ running shoe (rocking a patent-pending support mechanism that adapts to your gait as you run) steezed up with sky blue laces and red stars along the interior bottom that recall the Chicago flag, which is more than we can say for you, Mr-Play-Paper-Football-During-Social-Studies.
They've got a whole mess of other marathon-related gear at Nike.com
