In a recent journal article titled “The effect of walking in high and low heeled shoes on erector spinae activity and pelvic kinematics during gait” as published in the Archives of Physical Medicine and Rehabilitation 2012; 91: 425-434 it was found that wearing a stiletto type heel significantly increases lumbar muscle activity during gait in both younger and middle aged females. This may result in increased general and muscular fatigue, swelling and limited movement raising the possibility of cumulative strain.

Fashion over function is never a good thing as this article supports.
