Orthopedic shoes are the footwear that is very special and designed to cater for the people with various medical and bone abnormalities and conditions of the foot. These shoes are meant to ease the condition being suffered from and to stop it from worsening. Some of these conditions include arthritis, calcaneal spurs, pes planus and hallux valgus. The shoes also address the problems of abnormal shapes and sizes of feet which result in pain when wearing ordinary shoes. Your feet are important. If you have chronic back, knee, hip, foot and leg pain, get your feet checked because they may be the cause of your pain. Knee pain can result from a number of different structures and in a variety of ways. Patello-Femoral Pain Syndrome (PFPS) is a very painful condition. It is the most common overuse syndrome affecting the sporting population and 25% of the general population are affected at some time. Although quite debilitating, PFPS can be treated conservatively with appropriate physiotherapy (physical therapy) techniques and exercises. The knee is a simple hinge joint with slight accessory movements available to it. Primarily it extends and flexes the knee that is the joint between the Femur (thigh bone) above and the Tibia (shin bone) below. For women, wearing high heels is particularly challenging when they have flatfoot. In this case, wearing heels too high can cause problems with the Achilles tendon. Furthermore, it can even affect the motion of the ankle. Many women who have flatfoot find that wearing shoes with a wedge heel are more comfortable than ordinary high heeled shoes. The wedge heel offers a level of firm support that spindlier heels do not. There are also special pads which can be placed into the shoe, which provide somewhat of an artificial arch. These pads can be found in many drugstores. Or you can have a specialist to prescribe orthotics upon further evaluation. Having a knowledgeable runner or coach evaluate your running form and your stride may be especially helpful if a flaw in your running style can be identified. Changing the way you roll your foot from heel to toe can often be adjusted, or even how your foot strikes the ground can decrease the stress on the inside of your foot. The wear on your running shoes can also offer clues. If more wear is on the inner part of the shoe, you should investigate whether your stride can be altered and whether different shoes can provide the support and flexibility for a healthier step. Studies suggest 20-30 percent of all people suffer from flat feet. Duck feet, as some may call it, is medically describes as pes planus Though flatfoot is a well recognized diagnosis, its cause is not as well defined. Flatfoot can be seen in young children and is actually considered normal up to the age of two or even five years old. Some flatfoot conditions occur much later in life and in reality; flatfoot can be encountered at any age and cause a broad range of pain from absolutely none to physically debilitating. The condition of flat feet is also known as pes planus. Pes planus is a condition that affects the arch or instep of the foot, according to the University of Maryland Medical Center. The arch collapses, and the entire sole of your foot touches the ground when you walk. You can be born with this condition, meaning that the arch of your foot never develops as you grow, or you can acquire flat feet in adulthood if the arch of your foot falls. In children, a condition called tarsal coalition can cause flat feet. Tarsal coalition can limit motion and lead to acquired flat foot.
