Massachusetts- Look out, Heather Mills McCartney! Female amputees are giving the gorgeous former model a run for her money with a new sexy, shapely leg created by a Wakefield man. Paul Harney has developed the LISA (Lightweight Inconspicuous Shapely Active) leg for amputees who want to wear high heels and don’t want unsightly lines on their backsides – often caused by the prosthetic limb’s edge. “What women want is a functional, pretty leg. Women can wear a 2-inch heel with this leg and go barefoot,” said Harney, owner of the FDR Center for Prosthetics and Orthotics, Inc., in Nashua, N.H. Olga Vigna, a Russian-born woman living in Belmont, developed a disease at a young age that prevented her left leg from growing. Doctors amputated it when she was 19 so a prosthetic leg would fit better. Vigna, 32, loves her new LISA leg. She wears it to work and to clubs. “It’s very beautiful and very sexy. I can wear jeans. I can wear a skirt,” said Vigna, who works at FDR. “It allows you to adjust your shoe so you can wear sneakers and high heels when you go out.” “You don’t feel sexy when you have a bad prosthesis,” Vigna said. “You want to have the same leg like any other person does.” Typically, the edge of a prosthetic leg fits up near a woman’s pantyline. Harney’s new leg is cut lower so no embarrassing lines show through pants and skirts. “Trying to hide those edges had been a problem,” Harney said. There’s a smaller knee and a button by the ankle that can be pushed to adjust the angle of the foot, which allows people to wear heels and flats or go barefoot. The legs are custom-made and cost between $12,000 and $14,000. Men also can wear one. “If a man wanted to wear a cowboy boot – that’s the foot he would want,” Harney said. Mills, who is married to former Beatle Paul McCartney, lost her leg in a 1993 motorcyle accident.
