Axons transmit the electrical signals to and from the brain, and myelin sheath acts as insulation, speeding up the signal and nourishing the central axon. Some forms of CMT affect the axon – making the signal to and from the brain weaker and less efficient. Other forms of CMT affect the myelin sheath, slowing down the signal. But even if the myelin is the problem, until there is damage to the axon there will be no symptoms of CMT. Without an intact axon and myelin sheath, your nerves are unable to activate target muscles or relay sensory information from your limbs back to the brain. Your orthotics, naturally, will feel a bit foreign in your shoes for a few days. If you find your orthotics are still uncomfortable after two or three weeks, check in with your podiatrist; your orthotics may need some adjusting. I recommend wearing your orthotics one hour the first day and increase by an hour each day. Are you looking for a natural treatment for cracked heels? This can be a very embarrassing skin condition. If you have dry and cracked skin on your heels that is preventing you from wearing sandals, then you need to learn about some of the best kinds of treatments for it. Don't let the symptoms of high arch feet scare you in the sense that you are not allowed to participate in sports such as running or jogging. With advance technology that's available today, shoe manufacturers are able to create a shoe for people what have high arch feet Just in case you are experiencing pain and would like to relieve the pressured areas, you can always purchase and use orthotics to relieve some of the pain. Have your foot measured each year. Adult feet can grow and change with age. Make sure you are standing when you have your feet measured, as your body weight expands your foot size. Dancers with a naturally high and flexible foot tend to get all the way up—or too far over—their shoes. Many will stand up on the whole platform of the pointe on their first try. They have an easier time finding their balance, and don’t have a problem getting up on pointe. They do, however, tend to have more trouble controlling their going down. I see a lot of new pointe students with high arches go up no problem, but then clop down on their heels, or shake when they’re up there. Even if you have no risk factors, wearing high-heeled shoes (especially spike heels) can still cause problems, such as shortening of the Achilles tendon. They also increase stress to the ball of the foot. This can lead to bursitis, synovitis (inflammation of joint fluid) and even nerve irritation. Even lower-heeled dress shoes, including men's professional footwear, can lead to arch strain, tendonitis and PF. If you'd like to wear heels (who doesn't want to appear taller?), they should be no more than 2 inches. For people who insist on sandals, ask a podiatrist about custom-made sandals, in which arch supports are crafted right into the body of the sandal.
