London, Feb 2 (ANI): It looks like killer heels are not just a sexy accessory - they are a way of getting a fabulous set of pins.
According to a new research, stilettos give the legs a great workout, and make them more shapely and toned.
The study of women aged 18 to 33 revealed that walking in high heels activates inner and outer calf muscles more evenly than wearing flatter shoes.
Women who preferred to wear lower heels had bigger inner calf muscles.
"Similar to pulling a door closer to its hinge, the ankle must be extended by a greater force when muscles pull closer to the ankle joint with a shorter heel," the Daily Express quoted Biology professor Anna Ahn, of Harvey Mudd College in Claremont, California, as saying.
"In order to generate these higher forces at the ankle, these individuals activate their relatively thicker muscles for longer," Ahn added.
The research was published in the Royal Society journal, Biology Letters. (ANI)
