A new, limited-edition shoe from Adidas-Salomon AG, part of the \"Yellow Series\" and decorated with the face of a character who has buck teeth, a bowl haircut and slanted eyes, has provoked a heated debate about the lines dividing racism, art and commerce. Frank H. Wu, dean of Wayne State University's Law School, says the images have an effect that cannot be ignored. \"The problem with this is not that it\'s done by bigots, because it\'s not,\" he said. \"It\'s also not that it offends people, because in many ways, that\'s what art is meant to do. The problem is that these images, even though crude and clichéd, are powerful, almost indelible. They write the scripts that we expect others and we ourselves to follow. You can\'t read all that into a shoe, but it\'s part of a pattern.
