I thought this pair of Forza Badminton Shoes looks very similar to the Adidas Barricade Tennis Shoes. Are the outer soles suitable for indoor courts? http://www.fz-forza.dk/Default.aspx?ID=101&ProductID=PROD410&PID=438
"NON-marking ydersål" I actually saw one of the german player's with it (Kindervater). Thought they were adidas at first as well ... Don't think they are part of the adidas group though.
