At TOMS Shoes I’m guessing it’s a 13DD because of its One for One mission: “With every pair you purchase, TOMS will give a pair of new shoes to a child in need.”

Why? Because in a 2006 trip to Argentina, Blake Mycoskie found many children without shoes, which meant they were at risk of soil-transmitted diseases, developing infected cuts and not being able to attend school because of uniform requirements.

Blake wanted to help, so he created TOMS and the One for One program. And as of September 2010, TOMS has given over one million pairs of new shoes to children in need.

TOMS is a truly sustainable business, but who will keep it growing? Gen X and Y. The ones who see corporate responsibility in terms of the environment and making the world a better place.

So TOMS reaches out to them now with its Campus Clubs program, encouraging them to help spread the word about conscious consumerism. By joining or starting a club, TOMS promises members experience in marketing, event planning, viral marketing and leadership.

“The world around you is waiting to be changed,” it says on the Campus Club web page. “It is waiting, desperately, for good ideas, and passion and belief. You don’t have to wait until you’re out of school. You don’t have to wait to be heard or to make a change.”
