If you'd like to walk in Madonna's shoes there's an auction for that. Celebrities from around the globe have donated their footwear to the Small Steps sale, which will be held on eBay on December 15, 2013. Items up for grabs include the heals Madonna wore on her MDNA tour, Taylor Swift's Keds, Vivienne Westwood's clompers (that have walked numerous haute couture catwalks) and Kate Winslet's satin YSL party sling-backs. Celebrity contributors hail from the world of sport, music, film, TV, fashion and the arts. Also for sale are Rafa Nadal's winning-Wimbledon sneakers, footwear worn by The Rolling Stones, Ricky Gervais, Kate Moss, Naomi Campbell, Elton John, Eminem, Florence Welch and many more. The Small Steps Project (SSP) is a British charity that delivers shoes, aid and sustainable solutions to children who survive by scavenging from rubbish dumps. SSP then helps these children enter education with an aim to break the cycle of poverty. Pictured: Topshop heiress Chloe Green
