In a 2012 study, researchers examined the risk long time high heel wearers would have in regards to calf Muscle fascicle length and strain. The control group consisted of women who wore heels for less than ten hours weekly and the experimental group consisted of women who wore heels for a minimum of forty hours weekly for at least two years. The experimental group was told to walk down a walkway barefoot and in heels while the control group walked down barefoot as cameras recorded their movements to calculate muscle fascicle lengths. The data showed that wearing heels shortened the length of the medial gastrocnemius (MG) muscle fascicles in the calf significantly as well as increasing stiffness in the Achilles Tendon. The experimental group also demonstrated a larger amount of strain on the muscle fascicles while walking in heels because of the flexed position the foot is forced into. The researchers were able to estimate that when wearing heels, the estimated fascicle strains were approximately three times higher and the fascicle strain rate was approximately six times higher. Additionally, they were able to conclude that the long term usage of high heels can increase the risk of injuries such as strain along with discomfort and muscle fatigue.

In 2016, scientists from the Department of Physical Therapy in the Sahmyook University in Korea conducted a study to examine the effects of increased heel height and gait velocity on balance control. Balance control refers to the ability of the body to maintain itself along the line of the center of gravity within a base of support. This must be achieved with minimal postural sway velocity which is the horizontal movement of a body trying to maintain balance when standing still. Wearing high heels narrows the base of support that the body has in order to avoid falling and also restricts the area within which the body must sway. In this study, the participants were told to wear either a low or high heel and walk at a low and high speed on a treadmill. As a result of this experiment, the researchers were able to conclude that as heel height increased, the sway velocity of the bodies increased which also modified the position of the knee joint. Muscles have to realign the entire body especially the hips along the line of gravity. As the weight of the body shifted forward, the hips were taken out of alignment and the knee joints experienced stress in order to adjust to the shift.

The design of the high French heels from the late 1600s to around the 1720s placed body weight on the ball of the foot, and were decorated with lace or braided fabric (pictured). From the 1730s-1740s, wide heels with an upturned toe and a buckle fastening became popular. The 1750s and 1760s introduced a skinnier, higher heel. The 1790s continued this trend, but added combinations of color. Additionally, throughout all of these decades, there was no difference between the right and left shoe.
