With a major celebrity shoe auction currently raising funds for children forced to live and work on rubbish dumps, we've compiled our list of the top 5 collectible shoes ever sold.
Back to the Future II Nikes
Around 10 pairs were produced for the 1989 movie, in which Michael J Fox et al head to 2015.
Last year Nike brought out 1,500 replicas of the famed shoes, with many selling at a charity auction on eBay.
Indeed, British rapper Tinie Tempah paid $37,500 for one pair, significantly more than the price of an original.
Usain Bolt's running spikes
A signed pair of Usain Bolt's running spikes sold for £25,000 ($38,744) in July 2012, just days before the Jamaican sprinter would begin his conquest of the London 2012 Olympics, winning gold in the 100m, 200m, and 4x100m relay.
Marie Antoinette's silk mules
A pair of size 3½ silk mules owned by the queen consort of Louis XVI, Marie Antoinette, sold for €43,225 ($57,350) earlier this year, smashing their €3,000-5,000 estimate.
It is thought she wore them during the Fete de la Federation on July 14, 1790 - the first anniversary of the storming of the Bastille.
Antoinette is famed for her love of fashion, with her overspending claimed by some to have contributed to the French Revolution by fuelling popular discontent.
Princess Diana's bridal shoes
Princess Diana's back-up bridal shoes, produced in case of a mishap with the first pair during her 1981 wedding to Prince Charles, sold for £36,000 ($56,600) in 2011.
Like the original pair, each shoe featured the initials C and D.
"She could have changed the left or the right and you wouldn't notice the difference," auctioneer Kerry Taylor told the Daily Mail.
"They were made in case her first pair got stained or damaged, or something happened to them on the day - these were kept just in case."
Dorothy's Wizard of Oz slippers
It is thought that at least five pairs of the slippers were made for the 1939 film. One of those five pairs achieved $666,000 at Christie's New York in 2000, while a pair worn by Judy Garland for the first two weeks of filming auctioned for $627,300 last year.
One of the pairs was stolen from the Judy Garland Museum in Grand Rapids in 2005. They have not yet been found.
