Kicks USA, a Philadelphia-based chain specializing in trendy sneakers, will make its Maryland debut this year with a new store at Westfield Montgomery Mall. The retailer will take over two storefronts near Macy’s Home that were previously occupied by Core, which closed this winter, and Voorthuis Opticians, which has relocated to the Nordstrom wing. Kicks sells shoes for men, women and kids, but its marketing is aimed squarely at teen boys who collect and trade the latest editions from Nike, Adidas, Vans and other popular lines. The company publishes a “release date” schedule for each new design, making savvy use of social media and fanboy videos like this one for the latest pair of Air Jordans.
