Wearing higher heels - although perhaps not stilettos - may improve your pelvic floor muscles and in doing so boost your sex life, a study suggests. An Italian urologist and self-professed lover of the sexy shoe set out to prove that high heels were not as bad for women's health as some suggest. The shoe has been linked to a range of problems - from corns to schizophrenia. But in a letter to European Urology, Dr Maria Cerruto said her research showed it was time to stand up for the heel. She said her study of 66 women under 50 found that those who held their foot at a 15 degree angle to the ground - the equivalent of a two inch heel - had as good posture as those who wore flat shoes, and crucially showed less electrical activity in their pelvic muscles. This suggested the muscles were at an optimum position, which could well improve their strength and ability to contract.
