Long before Sean John and J-Lo, Harput's was selling track suits. Long before Run-D.M.C., Harput's was selling Adidas. Originally run out of a minivan in the 1970s, Harput's put down roots on Fillmore Street 18 years ago, selling what it calls "old school" sneakers and track suits. These are the shoes and warm-up suits you remember from your youth -- the simple designs, bold colors, and sporty stripes of the 1970s and '80s. Though you can buy Nikes, Pumas, and Asics here, Harput's real stock in trade is Adidas. Just about any style ever made by Adidas (from any era, some imported from as far as Tokyo and Milan) is available. If you're not a track-shoe collector (and if you were, you would already have been to Harput's), there's plenty of vintage sportswear to get excited about. After an afternoon at Harput's, you'll be convinced there is nothing more bad-ass than showing up at the coffeehouse on a Sunday morning looking like Steve Prefontaine, in a matching mustard-and-green, 1970s-style track suit.
