There's all kinds of special clothing and uniforms that kids have to have to play sports, join the Boy Scouts, sing in the school chorus, etc. But one of the most expensive and least used are "specialty shoes". Baseball players, golfers, soccer players, etc. have to wear special "cleats" that can cost upwards of $100 new. A league with 10 teams and 20 players each means $20,000 worth of shoes. Per league. And since kids continually outgrow their shoes here's a business opportunity. Just like college bookstores do, you can buy the outgrown merchandise for a few dollars, and then turn around and sell it to others and instantly double your money. And if you give a contribution to the soccer club based on sales, you will undoubtedly get their attention and their approval.
