In a 2012 study, Kai-Yu Ho, Mark Blanchette and Christopher Powers, wanted to determine if heel height increased patellofemoral joint stress during walking.[25] The patellofemoral joint refers to junction where the femur and patella meet. The study consisted of eleven participants wearing tracking and reflective markers as they walked across a 10 meter force plated walkway in low, medium and high heels. The study showed that as the height of the heel increased, the ball of the foot experienced an increase in pressure resulting in increased discomfort levels and peak patellofemoral joint stress. The researchers also mentioned that the long term usage of high heels would lead to repetitive overstress of the joint which would result in an increase in pain and eventually, patellofemoral joint osteoarthritis and Patellofemoral pain syndrome.
Further research reveals that another possible consequence of wearing high heels is an increase of pressure in one's veins. Experiments have proven that the higher the heel, the "higher [the] venous pressure in the leg." This means that after repeated use of high heels, varicose veins and other undesirable symptoms are much more likely to appear in the legs.[18] Other research supports these two claims when arguing that wearing high heels can lead to numerous long term effects, including accidental trauma to multiple areas of the body.[4]

Heels went out of fashion starting around 1810, and then in 1860 they returned at about two and a half inches. The Pinet heel and the Cromwell heel were both introduced during this time.[12] Their production was also increased with the invention and eventual mass production of the sewing machine around the 1850s. With sewing machines, yields increased as machines could quickly and cheaply "position[n] the heel, stitc[h] the upper, and attac[h] the upper to the sole."[9] This is also a prime example of how the popularity of heels interacts with the culture and technology of the time.
