Bombas became known for donating one item for every item purchased through its buy-one-give-one model.
The company was founded in 2013 by Randy Goldberg and David Heath after they learned that socks were among the most requested items at homeless shelters. Bombas redesigned its socks with features such as a seamless toe and a blister tab, then tied each retail sale to a donation. The donated products are made specifically for charitable distribution rather than simply being identical retail pairs.
Bombas appeared on Shark Tank in 2014 and made a deal with Daymond John. The company later expanded from socks into other basics, including underwear and T-shirts. Its model is sometimes described generally as buy one, give one, but the exact donated item depends on the product purchased.
