Foot problems are one of the most common health complaints. The high incidence of foot problems is understandable given the fact that there are 26 bones, 33 joints, 112 ligaments, and tendons, nerves, and blood vessels in the foot. It’s even more understandable when the weight of the body is considered. The force of the body weight borne by the foot increases roughly 1½ times during walking and up to 3-4 times during running. Add in 10,000 steps during a typical day while wearing ill-fitted shoes possibly, and it’s a wonder one’s feet are willing to get out of bed the next day.
Not all feet are created equal. To tell what type of foot one has, one can get the bottom of the feet wet, stand ...view middle of the document...
For a motion control shoe the midsole likely is a firm, dual density material, denser on the inside at the arch and heel.
* The last refers to the method of attaching the upper to the midsole/outsole, and also the shoe curvature shape. A motion control shoe typically has a board last, with a straight to semi-curved last shape.
* The heel counter (the area surrounding the heel) is very firm to squeeze, providing stability in the heel
2. High Arched Foot (Supinator)
* The high arched foot tends to be a more rigid, less flexible foot with more weight borne on the outside part of the foot.
* Less shock absorption occurs in the foot. Consequently more forces are transmitted up the leg to the trunk.
* This person tends to wear out the outer side of the shoe from heel to toe. Calluses may be seen along the outer edge of the foot to the base of the 5th toe.
* If this person’s shoe is placed on a flat surface, the shoe may tilt outward.
* Problems seen with this type of foot include stress fractures in the tibia or femur, Achilles tendonitis, and plantar fasciitis.
* A high arched foot benefits from a cushioned shoe providing shock absorption. This reduces the amount of impact transmitted upwards through the legs.
* The midsole is a softer, more flexible, single density material, providing less support and more cushion.
* The last is a slip last (sewn down middle of shoe sole), with a curved or semicurved last shape.
3. Neutral Foot
* This is a more desirable foot structure. The foot pronates, or rolls inward, initially with weight bearing, but when the person is ready to push off with the forefoot and toes while walking, the neutral foot adjusts to provide stability. The neutral foot therefore provides a combination of shock absorption and stability at the appropriate times during walking or running.
* An even wear pattern on the shoe sole is expected with a minimum of calluses.
* The neutral foot benefits from a stability shoe, which...
