Sportswear and athletic footwear giant Reebok on Wednesday revealed its first signature athletic shoe line for a non-athlete, hip-hop star Jay Z's S Carter Collection, had become its fastest ever selling shoe. The company said the line, named after the star's real name, Sean Carter, had even outsold its Allen Iverson basketball shoes with one source saying the firm had sold 10,000 pairs of the $150 shoes within an hour of them hitting stores.
