If you have a high arch, you may develop calcaneal inversion, calcaneal meaning the heel and inversion meaning that the heel move inward when you run. Also known as supination, calcaneal inversion can affect the way you move and your ability to run without pain. Supination is less common than overpronation, a rolling in of the foot, according to the Sports Injury Clinic. Orthotics, specially designed arches that fit into your shoes, may decrease discomfort and further injury by stabilizing your foot as you run.

Understanding Calcaneous Inversion

If you have normal foot alignment, the back of your heel forms a fairly straight line if you draw an imaginary line up your leg. Supination causes the outside of your foot to roll outward. Oversupination can cause shin splints, ankle sprains, plantar fasciitis and stress fractures of the heel as well as the tibia,one of the lower leg bones and the toes. An orthotic to correct supination helps correct the alignment of your foot to balance your high arch.

Common Causes of Supination

A high arch, which is often an inherited characteristic, causes supination. If you have a high arch, you tend to have a more rigid foot and walk more on the outside of your foot, which puts undue strain on your legs. The bones, muscles, tendons and ligaments shift to accommodate the changes in the foot, leading to increased risk of injury while running.

Orthotic Types

You can buy orthotics molded specifically to your foot or orthotics sold commercially, which may or may not help your particular foot problems. If your foot oversupinates, you need orthotics that redistribute the weight over the entire foot rather than on the edge. A custom-made orthotic is made after your medical provider makes a casting of your foot. The orthotic made for you may differ considerably from someone else's even if you both have supination. Your own two feet may vary in the orthotic structure needed to correct the abnormalities.

Considerations

Custom-made orthotics are expensive, but if you're a serious runner, they can prevent many injuries and leg and foot problems down the road. You may need orthotics in addition to a more flexible, cushioned running shoe that will better absorb shock, certified athletic trainer Kara Frey of UK Health Care Sports Medicine states. Make sure to try new shoes on with your orthotics, to be sure they fit comfortably and try shoes on at the end of the day, when your feet are at their largest.
