Ricosta, the major German brand of children's shoes, is showing for the first time at the OutDoor fair in Friedrichshafen this week, following its successful introduction of its first styles of outdoor shoes a couple of years ago. They are particularly strong in the German-speaking countries and Russia. On the other hand, Ricosta has announced that it will no longer exhibit at the GDS show shoe in Düsseldorf from next year on because of its late dates. Its participation in the fair next Sept. 5-7 will be the last one, and it will be accompanied by a special presentation. Ralph Rieker, president of Ricosta, is also the president of HDS, the German shoe and leathergoods industry association.
