A pair of knee-high, black leather platform boots custom made for Sir Elton John are up for auction as part of a bid to raise funds for human rights organisation Amnesty International.

The footwear, signed 'With love, Elton John x', and decorated with a giant gold piano motif, are to be placed on Internet auction site eBay.com.

To help bump up the bids, Sir Elton has thrown in a pair of tickets to see him perform at the Bestival festival on the Isle of Wight next month (08Sep13).

Other items up for grabs in the auction include signed memorabilia donated by Coldplay and Genesis.

Bidding closes on 1 September (13).
