Brandon Martinez, 12, and Sebastian Martinez, 10, run the 'Are You Kidding?' sock company, a business they started in 2014.

Since then, the brothers have created at least 30 different designs and raised thousands of dollars for charities that support kids. InsideEdition.com's Lisa Voyticki has more.
