Adidas' growth shows no signs of slowing, and the brand has reportedly surpassed Jordan to become the second biggest in the U.S. sneaker market. The news comes from Matt Powell of the NPD Group, who posted a series of tweets on recent industry sales figures on Monday.

Adidas' current share of the U.S. sneaker market sits at 13 percent, according to numbers from the NPD Group, a market research company that tracks, among other things, sales at sneaker stores.

Powell's sales reports have models like the Adidas Tubular Shadow and Superstar as some of the top-selling sneakers in August.
