Women have been wearing various kinds of high-heels for hundreds of years, mostly for aesthetic reasons. Shoes with heels make their wearer appear to be taller and to have longer and thinner legs, and change the wearer’s gait and posture. High-heels’ association with femininity have kept them popular over the years, but there are definite health problems caused by wearing high-heels too frequently.
High heels also limit the motion of the ankle joints as well when they are worn. The ankle is a very important joint in the body when it comes to walking. These joints have a great deal of weight put on them because of their location. This is why it is so important to keep them as healthy as possible. The main tendon in the ankle is the Achilles tendon. Studies have shown that wearing high heels often causes the calf muscle and Achilles tendon to shorten, and stiffens the Achilles tendon as well, which can cause problems when shoes without heels are worn.
By forcing the toes into a small toe box, and putting a great deal of pressure on the ball of the foot, high-heels can cause or worsen many foot problems, such as corns, hammertoe, bunions, Morton’s neuroma and plantar fasciitis. 

Wearing high-heels regularly, especially very high ones, can have long term negative effects on many other parts of the body, as well as the feet. One of the most important joints in the entire body, the knees, can be affected by wearing high heels. Wearing high heels causes the knees to stay bent at all times. It also causes them to bend slightly inward as well. Many doctors believe that constantly walking like this is the reason that women are so much more likely to suffer from osteoarthritis later in life. High-heels also cause increased stress on the knees by limiting the natural motion of the foot during walking.
The back may also be negatively affected by high heels because this shoe style causes the back to go out of alignment. This affects the spine’s ability to absorb shock, and can cause continued pain in the back if high heels are worn constantly. High-heels also compress the vertebrae of the lower back, and can cause overuse of the muscles in the lower back.

This is not to say that high heels should never be worn. They will not cause serious problems if they are worn only occasionally. However, they should not be worn every day in order to avoid long term physical health problems to the feet, knees, ankles and back.
