Topeka-based Payless ShoeSource is closing all 2,300 of its domestic retail stores, a company spokesperson confirmed to KCUR on Monday. About 1,200 retail stores outside the U.S. are not affected. The news was first reported by Reuters on Friday. Sources told the news service the company plans to file for bankruptcy, less than two years after emerging from bankruptcy in 2017. The company began liquidation sales at its American stores on Sunday. Online sales are also being eliminated.
