Walmart claims the shoe was being sold by a third-party seller and that they had nothing to do with the knock-off.
Kanye West has always been very protective of his intellectual property and he has every reason to be. After all, his Yeezy brand has turned him into a billionaire and if his ideas get stolen, he can lose out on some pretty massive sales. Not to mention, knock-offs of poor quality can do significant damage to his reputation. With this in mind, it should come as no surprise that Kanye is going after Walmart after a Yeezy Foam Runner clone was sold on their website.
