Celebs and fashionistas are known for falling head over heels for shoes, but these days some women are doing it literally. Lady Gaga, Mariah Carey, Beyonce and several supermodels have been known to stumble in some very high heels and designers are getting more creative. The next up-and-coming stilettos include animal-inspired heels, some as high as 11 inches. German shoe designer Iris Schieferstein's shoe line includes some of the most bizarre touches, including these bovine hoof-inspired shoes with pistol-shaped heels. (Courtesy Iris Schieferstein)
