Wal-Mart can't avoid sneaker copyright lawsuits these days. Last month the chain settled a trademark-infringement lawsuit with Adidas after Adidas accused them of knocking off their triple-stripe logo on sneakers. But now Nike's slapped Wal-Mart with another copyright-infringement lawsuit. The athletic brand says Wal-Mart's Shox footwear are too close for comfort to Nike Shox (the running shoes with the coil heels). Wal-Mart's version cost only $10 or so — a tenth of what the Nike kicks retail for at Foot Locker. [DNR]
