Pronation is the inward movement of the foot as it rolls to distribute the force of impact of the ground as you run. The foot "rolls" inward about fifteen percent, comes in complete contact with the
ground, and can support your body weight without any problem. Pronation is critical to proper shock absorption, and it helps you push off evenly from the front of the foot. Although pronation is a
natural movement of the foot, the size of the arch can affect its ability to roll, causing either supination (underpronation) or overpronation. If you have a normal arch, you're likely a normal
pronator, meaning you'll do best in a shoe that offers moderate pronation control. People with flat feet normally overpronate, so they do well in a motion-control shoe that controls pronation.
High-arched people typically underpronate, so they do best in a neutral-cushioned shoe that encourages a more natural foot motion.
You do not have to be a runner or athlete to suffer from overpronation. Flat feet can be inherited, and many people suffer from pain on a day-to-day basis. Flat feet can also be traumatic in nature
and result from tendon damage over time. Wearing shoes that do not offer enough arch support can also contribute to overpronation.
When standing, your heels lean inward. When standing, one or both of your knee caps turn inward. Conditions such as a flat feet or bunions may occur. You develop knee pain when you are active or
involved in athletics. The knee pain slowly goes away when you rest. You abnormally wear out the soles and heels of your shoes very quickly.
Bunions, calluses and crooked toes may indicate alignment problems. So, it is important to ascertain the condition of a client's toes. Check the big toe to determine if the first joint of the toe is
swollen, has a callus or bunion, and/or looks as though it abducts (i.e., hallux valgus) rather than pointing straight ahead. Also, look to see if the lesser toes seem to "curl up" (i.e., the person
has hammer or claw toes). This may be indicative of damage to, or inflexibility of the plantar fascia caused by excessive flattening of the foot.
Non Surgical Treatment
Fortunately, there are simple things you can do to cure and correct your overpronation issues. Certain exercises help. Pull your toes back using a rolled up towel. Roll your feet over a golf or
tennis ball for a minute. And do calf raises by standing up and lifting up on your toes. These all help reposition the foot and strengthen the muscles and tendons necessary for proper support. Beyond
that, simple adjustments to footwear will help immensely.
With every step we take, we place at least half of our body weight on each foot (as we walk faster, or run, we can exert more than twice our body weight on each foot). As this amount of weight is
applied to each foot there is a significant shock passed on to our body. Custom-made orthotics will absorb some of this shock, helping to protect our feet, ankles, knees, hips, and lower back.
