The feet are the "walkway to the world." However, constant wear and tear on the feet can lead to injury. Insoles can provide an extra cushion or shock absorption in the shoe to help protect the joints of the ankle and knee. The inside arch of the foot is considered a "shock absorber" and has an important role in maintaining good posture. If the arch is overstressed, complaints of heel pain especially when weight is placed on the foot may result. Plantar fasciitis, or heel spur syndrome, may occur from a poorly supported arch. As a result, shoes with a good arch support are important for foot health--insoles can assist with this support.
What to Look for
Insoles come in a variety of styles and sizes for both men and women. When choosing an insole, start with foot or shoe size. The best choice for an insole is one that is solid and has a nice arch support. Most importantly, the insole should match the arch of the foot. Some insoles may require cutting to fit the shoe, but the arch support should remain intact and in proper position. Recently, an insole has been created to fit a high heel shoe for women.
The more expensive option for an insole is orthotics, obtained through a podiatrist or orthopedist. To create a custom arch support, the podiatrist creates a mold of the foot in the relaxed position. This mold is then used as a template to create orthotics often made of fiberglass or some other extremely durable material. This material can withstand the wear and tear of the feet and shoes. Orthotics are expensive but very durable.
Common Pitfalls
When wearing insoles, shoes may be a bit tighter. Try the shoe on with the insole inside to make proper adjustments and to ensure a snug fit. Also, insoles should not be used to prolong the life of older shoes. Shoes naturally wear down and eventually do need to be replaced. Unless professional orthotics are used, over the counter insoles need to be replaced regularly. When foot pain returns or the knees begin to ache, it may be time for replacements.
Some over the counter sport insoles, however, do not provide the support needed during activity. If the insole comes in a "U-shape" with an empty space in the center, it will not provide good foot support. With each step, this "U-shape" widens from body weight and may become misaligned, decreasing arch support. Insoles should be solid to provide ample support. Also, most experts suggest insoles do not significantly increase the needed cushioning for shock absorption. Proper fitting athletic shoes provide sufficient cushioning.
Therefore, adding insoles to athletic shoes may just make the shoes more comfortable.
