Rita Ora, Tom Odell, Ronnie Wood, Niall Horan, Sharon Osbourne, Keira Knightley and Sir Lewis Hamilton are among stars signing and donating footwear to Small Steps Project's annual celebrity shoe auction, running until November 11.

All proceeds will go towards providing emergency aid, shoes and food to children and communities living on rubbish dumps worldwide, and Odell commented 'To survive off landfill sights is a nightmare no one should have to endure, especially children. The work Small Steps do is truly inspiring and the shoe auction is a great way of raising money. I am glad some of my old shoes can help contribute'.
