Footwear has long been immortalized in song: Run DMC rapped about Adidas, Nelly had his Air Force Ones, and hundreds of artists have belted out covers of Tommy Tucker’s 1964 blues cut “Hi-Heel Sneakers.” It’s possible that the bards will sing of this day, too, because this weekend marks the return of the footwear convention Sneaker Con to the Atlas Performing Arts Center. The Adidas-sponsored event is the best place for fresh-rubber-craving sneaker heads to buy new and vintage styles from licensed vendors, with more budget-conscious ballers having the option of trading or buying used shoes. And this time they get an extra day to do it: After the huge success of the first local Sneaker Con in April, its New York-based hosts are remounting it for two days. With co-sponsors like Freshness magazine and, the event should attract purveyors of only the flyest kicks—and who knows, maybe the parade of sensational sneakers will inspire them to pen their own ballads.

Sneaker Con runs from noon to 7 p.m. through Sunday at the Atlas Performing Arts Center, 1333 H St. NE. $12.
