The footwear is a very important factor in the biomechanics of the foot, the leg and even the back. Inadequate footwear can cause injury. For example, shoes that are too wide at the heel can cause a very painful irritation under the foot, plantar fasciitis, often associated with a problem called Lenoir’s spine.
The explanation: there is, under the heel, a small cushion of adipose tissue whose function is to absorb the shocks caused by the impacts of the foot on the ground. Now, if the heel of your shoe is too wide, this cushion has space to spread, it thins and protects you less and less. In addition, a shoe that is too wide does not support the arch of the foot. These two phenomena combine to cause plantar fasciitis.
The risk of fasciitis is also increased by wearing rubber flip-flops, very popular in the summer. These shoes offer no support. They can cause sagging of the arch, as well as knee problems, especially in people with flat or hollow feet. The lack of support of the arch modifies the biomechanical alignment of the leg, resulting in problems of kneecap, or tendonitis in the knee or the ankle.
High heels should be worn only occasionally. If they are part of the daily routine, they risk shortening the calf muscles and causing inflammation of the Achilles tendon, making it difficult to walk barefoot. They can also increase the risk of plantar fasciitis. On a daily basis, a comfortable heel of two or three centimeters is recommended. (more…)
