As the holiday season approaches, what better time to put your best foot forward and give back to the causes and organizations you care about? The Barefoot Wine Beach Rescue Project is hosting an online charity auction of shoes belonging to beach-loving celebrities in an effort to raise awareness and generate funds to support the Surfrider Foundation ? a grassroots, not-for-profit environmental organization dedicated to the protection and enjoyment of the world’s oceans, waves and beaches.

To create the collection, Barefoot Wine asked actors, athletes and musicians to help “heel” America’s beaches by kicking off their shoes and donating them in support of more “barefoot-friendly” beaches. Notable surfing enthusiasts going barefoot for the cause include: actors Matthew McConaughey, Cameron Diaz, Sophia Bush and Andrew Keegan, athletes Kelly Slater and Lisa Andersen, Host of E!’s Daily Ten and the X-Games Sal Masekela and musicians Jack Johnson, G. Love (of G. Love and Special Sauce), Matt Costa, Nick Hexum (of 311) and Tristan Prettyman.

The autographed shoes will be listed on eBay’s Giving Works, which empowers people to buy and sell for a cause. The charity auction will begin at 4:00pm PST on Tuesday, December 2 and end on Friday, December 12. Visit www.eBay.com/BarefootWine to view Sophia’s shoes and place your bids
