Sarah Jessica Parker, Daniel Radcliffe and Coldplay rocker Chris Martin are among the stars who have donated a pair of their shoes to an online charity auction.

Ben Stiller, Kristin Davis, Brian May, Ricky Gervais, Morgan Freeman and Dame Judi Dench have also handed their footwear to the Small Steps Project, which delivers aid to children living on rubbish dumps in impoverished nations around the world.

Martin has given up the boots he wore while recording Coldplay's latest album Mylo Xyloto, Ronnie Wood's shoes have been hand-painted and supermodel Kate Moss has signed her autograph in the pink lining of her Mulberry heels.

A pair of Stefanel sandals have also been put up for grabs by actress Sienna Miller, who says, "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."

Lulu, Kevin Bacon, Ralph Fiennes, Liam Gallagher, Sir Tom Jones and Danny Boyle have also contributed shoes to the auctions on
