The second I chucked my Jimmy Choo shoes in favor of flats I read about Stiletto Spy School for Women. Power has always been an aphrodisiac — for men. But when a woman is called powerful it’s often code Bitch. Combining sexiness with power creates the potent combustion of a femme fatale, a woman who is feared and desired. Men may even delight being controlled by her while conspiring to take her down. Think Angelina Jolie in the movie Mr. & Mrs. Smith and the current film Salt. Of course, unlike most of us, Angelina Jolie, is sexy in sneakers.
