"There is a strong contemporary association between high heels and female sexuality.
We investigated the hypothesis that one motivation for women wearing high heels
is that it artificially increases the femininity of gait.
Biomechanical analyses revealed that wearing high heels led to increased femininity of gait
including reduced stride length and increased rotation and tilt of the hips.
This groundbreaking study was published this month in the scientific journal Evolution and Human Behavior.
It was written by Paul H. Morris, Jenny White, Edward R. Morrison and Kayleigh Fisher"
