Alex Fleming now employs two, ships to 50 countries and has supplied players at Sheffield’s two professional teams including Enda Stevens and Jayden Bogle at United, and Owls’ vice-captain Liam Palmer.
He has also sold to players in the Premier League, MLS and La Liga.
The 26-year-old started two years ago selling second hand boots on auction website eBay.
This year, through his own website at arffootball.com, he sold £150,000 worth of products and is targeting £200,000 next year.
His success has allowed him to quit his job in the construction industry and run the business full time.
His uncle, Andrew Fleming, said: “I'm a bit biased, but I think this is a great story of a young, local man who has built a thriving business despite all the problems facing businesses in the last couple of years.”
