Billions of children can't afford something as simple as a pair of shoes. Without shoes, these children are prone to disease, can't travel to clinics or food, and can't get in to some schools. In 2006, Blake Mycoskie started TOMS Shoes, a movement to end this problem. His company matches every pair of shoes purchased someone purchases for their own use with a pair of shoes given to a child in need. The company has already given 150,000 children shoes, and hopes to give twice as many in the coming years.
