Simple: For the folks at Simple, "How we make our shoes is just as important as WHY we make them."  For them, "that means finding more sustainable ways of doing business so we can make more. The important thing is we are committed to making our products 100% sustainable. Finding materials and processes that make our products sustainable is a method we call Green Toe. It isn't a magic formula, or a cure. It is a compass that, we hope, points to a bright green future." Great looking foot wear that supports the earth.
