Celebrities including Kate Moss, Keira Knightley, Margherita Missoni, Sienna Miller, Sarah Jessica Parker (and more!) have each donated a beloved pair of shoes to the 2012 London Celebrity Shoe Auction.

The auction will benefit the Small Steps Project—a UK-based organization that runs campaigns and events, such as the shoe auction, to raise awareness about children and communities living on municipal garbage dumps around the world. Last year's auction raised more than $30,000.

"These shoes were given with love. I loved dancing the night away in them and hope they can bring as much joy to someone else. It's a privilege to be able to donate to such a worthwhile charity," Sienna Miller said in a statement.

Each celeb who donated a shoe also autographed them.
