Thomas Lange, who started Keen Europe together with Richard Litzel and two other managers 13 years ago, is leaving the company in mid-October to become the new general manager of GEB, a German voluntary group of shoe retailers specializing in higher-end footwear. The members include big names like Prange and Tretter. They are all German except for Schuhaus Imgrüth from Luzern, Switzerland. Lange started off as Keen Footwear's sales manager for Germany, Austria and Switzerland at the end of 2005. He has been the European sales director for the American brand since the foundation of Keen EMEA in the Netherlands in 2008.
