TOMS Shoes was founded on a simple premise: With every pair you purchase, TOMS will give a pair of new shoes to a child in need. One for One. Using the purchasing power of individuals to benefit the greater good is what we're all about. The TOMS mission transforms our customers into benefactors, which allows us to grow a truly sustainable business rather than depending on fundraising for support.
That paragraph was taken from tomsshoes.com. In my opinion, genius.
