Steve Madden have responded to a lawsuit from AirWair Intl, Dr. Martens’ affiliate company. The lace-up high-top boot with rubber sole raised concerns over its alleged use of Dr Martens’ trademarked rubber sole. Steve Madden rejected these claims, and said that their use of design on the rubber sole was purely functional, and not a copy, also asking the U.S. Patents and Trademarks Office. AirWair and Dr Marten have requested a permanent injunction on the sales of Steve Madden’s boots, and $1 million in damages.
