Jack Johnson, Kelly Slater, Lisa Andersen and other surfing celebrities go barefoot for charity.

Several eco-minded celebrities are offering you the very shoes off their feet to support the Surfrider Foundation.

Cameron Diaz, Matthew McConaughey, Jack Johnson, Sophia Bush, Kelly Slater, and many others have put a pair of their shoes up for bid. This fundraiser is part of The Barefoot Wine Rescue Project, which is a long term initiative started by Barefoot Wine and The Surfrider Foundation to make America's beaches barefoot-friendly.

"This charity auction is an additional step towards improving the state of our coastlines," said Matt McClain, Director of Marketing and Communications for Surfrider Foundation. "We're stoked and grateful to see some of our long-time celebrity supporters kicking off their shoes and going 'barefoot' for the Surfrider Foundation."
