This bizarre range of shoes may make the owner feel like they have one foot in the grave.Crafted from dead animals, Iris Schieferstein's outlandish designs fetch up to £3,900 and have proved a hit with extreme dressers such as Lady Gaga.Some of the most controversial pieces include a pair of sandals sporting stuffed doves with their wings spread wide and a collection of heels fashioned from hollow horse hooves.The 45-year-old designer, from Berlin, Germany, collects carcasses from her local butcher which are discarded after the meat is used for sausages.She spends a week stripping out any remaining meat and bones from the animal's feet and the skin is sent to a tanner to be treated for preservation. The sculptor then sets the skin - complete with fur still in place - around a shoe model before hand-stitching insoles and lining.She said: 'Creating the shoes is ugly work, taking the meat out is not nice, like any taxidermy.'When I began working with dead animals I would pick them up from the street.'But they are protected by the government in Germany, and so after ten years they tried to put me in prison. Now I use my butcher.'The horse boots feature horse fur, a zip up the front, an intact hoof and horse bone as a heel.While a pair of snakeskin stilettos feature a replica pistol as a heel with the reptile seemingly eating its own tail.Describing her inspiration Ms Schieferstein added: 'I love horses and I love shoes so I thought this would be perfect.'Horses have a beautiful walk and I wanted to recreate that with my footwear.'The footwear has been displayed at numerous exhibitions around the world and have even inspired a range from Dolce & Gabanna.Despite the high price tag the footwear can only be worn for several hours at a time before becoming too uncomfortable.Ms Schieferstein said: 'As yet no company has been willing to produce them for the high street.'Last year the artist made a pair of custom-fit shoes for Lady Gaga.
