The Journal of Experimental Biology published a study that indicates high heels are harmful. Leg sonograms of women who frequently wear 2-inch or higher heels found that these women had thicker & stiffer Achilles tendons and calf muscle fibers that were ~13% shorter than women who don't. The calf muscle size was the same, however.
What should high-heelers do? Just stretch after you take your high heels off.
