Scientific Fit Dispels Myths
By Edith James, Certified Pedorthist
It is recommended that you have your feet scientifically fitted
every two
years. Most people think they are
full-grown at the age of twenty. In
truth, our feet flatten and elongate throughout our lives.
They do not actually “grow,” but the complex systems of ligaments and
tendons stretch, elongating the size of our feet. A half size is the equivalent of 1/6th of an inch
and a whole size is only 1/3rd of an inch. Therefore, increasing your shoe size occasionally is
necessary for foot health.
What do we mean by “Scientific fit?” It consists of matching the foot length and foot shape with shoes of comparable size and shape. There is no standardization in shoe sizes, they vary widely! Many people are stuck on size rather than “fit.” Several different sizes may be necessary to properly fit different styles and brands.
In our culture, many myths exist about shoe fit. Most people believe that in order for the shoe to “fit” or stay securely on the foot, the heel must fit tight. If the heel is tight in a new, stiff shoe, the toes must be jammed against the front of the shoe. This is how pumps are held on, a type of footwear that is responsible for many foot problems. Contrary to this myth, loose heels do not cause blisters. Friction from heels too tight and worn too long cause blisters. Loose heels indicate a healthy amount of toe room in stiff-soled shoes that are the best source for long-term foot health. A true walking shoe bends with your foot and there is absolutely no need for the heel to fit tightly. Your feet should be cradled, not bound.
Another myth is that shoes get longer as they “break-in.” In reality, shoes get shorter. The creasing that occurs at the ball of the shoe actually causes shoes to shorten. Scientific fit dictates that there be 1/3rd-½” length in front of the longest toes so the shoes will not become too short as they “break-in.”
The arch measurement of most people is longer than the heel to toe measurement. Fitting the ball of the foot to where the shoe bends is another element of Scientific Fit. If the shoes are short and the ball is too far forward, abnormal stress is placed on the joints. If the longest toes are at the ends of the shoes, the force from the ground in each step can be transferred to the joints of the feet and ankle. The faster and heavier the steps, the greater the forces (Force = mass X acceleration).
Pedorthists are the pharmacists of the shoe industry. Pedorthists design, manufacture, fit, and modify shoes and foot appliances for the amelioration of painful or disabling conditions of the foot and limb. Pedorthists are experts in proper shoe fit and work with physicians to relieve patients foot and lower extremity disorders.
