Foot type
Foot type is determined by the shape and structure of the foot. Foot type affects the reduction of impact on the foot while walking, jogging, or running. Specifically the shape of the arch causes different levels of pronation in feet.
Pronation
Pronation is the rolling motion of the foot from heel to toe while walking, jogging, or running. Pronation includes Neutral Pronation, Underpronation, and Overpronation.
Neutral Pronation
Neutral Pronation is hitting the outside of the heel and ball of the foot evenly across the foot to properly reduce impact on the foot. Medium arches are often neutral pronating foot arches, though oftentimes high arches can also neutrally pronate.
Underpronation
Under-pronation occurs when more weight is absorbed by the outside of the foot rather than evenly through the foot strike.
Overpronation
Overpronation occurs when there is too much roll on the inside of the foot, consequently distributing the weight and shock of impact more heavily on the inside of the foot rather than evenly throughout the foot as found in Neutral Pronation. The knee cap may therefore slant inward, and roll over the inside of the thigh, causing pain. An inward slant often requires a shoe slip or orthotic under the inside of the heel to return the foot to a Neutral Pronation. In addition, exercises which strengthen the inside thigh-muscle are often helpful.
Determining Pronation
Pronation will likely be evident by looking at the wear inside or on the rubber sole of a shoe. If the inside side is more worn than the rest of the shoe then the person overpronates. When the outside side of the shoe is more worn than the inside side then the person underpronates. If the wear is equal across the forefoot then the person is a neutral pronator, or has neutral stride.
Arch
The height of the arch in the foot determines pronation, and therefore, foot type.
Determining Arch Height
The arch height of a foot can be determined by a wet test. To take the test, stand normally on a paper bag for about ten seconds after wetting each foot. The resulting imprint will show whether the person has a medium arch, a low arch, or a high arch.
Medium Arch
People with a Medium arch have a distinct curve along the inside of the foot with a band slightly less than half the width of the foot connecting the heel and toe. People with medium arch are likely to have a neutral stride, although sometimes even medium arches can have their drawbacks and negative effects. Although sometimes called the "normal" arch, this may appear as a misnomer because nobody has 'normal' arches within their feet.
Low Arch
People with a low arch do not have a distinct curve along the inside of the foot. The imprint taken in a wet test will show nearly the entire foot. People with low arches are more likely to overpronate which can result in injuries.
High Arch
People who have a high arch in the foot show only a very thin band connecting the heel and toe in a wet test. People with high arches are more likely to underpronate although this isn't always the reality. Contrary to usual rhetoric, high arches will not always have drawbacks or negative effects. Many people prefer high arches because of various reasoning.
Studies of Arches
Studies for foot arches are oftentimes loaded with flaws and with mistakes or substandard research and data. Do your own researching for determining which arch suits you best and which foot arch you will prefer.
Pronation and Arch in Athletes
Athletes with different foot types should look for running shoes that specifically treat their arch and pronation to avoid injury. Running shoes generally come in straight, curved, and semi curved shapes.
Overpronators should wear shoes with a straight shape. Overpronators should also look for a motion control shoe, which prevents the foot from rolling too far by providing maximum support. Shoe manufacturers usually include a medial post or rollbar to accomplish motion control. The medial post is basically a solid piece of material on the inner part of the shoe that resists the inward roll of pronation. Orthotics are also a popular method of support for athletes who have flat feet.
Underpronators should wear a shoe with a curved shape. Underpronators should also look for a cushioned shoe to allow the feet to roll inward and absorb shock.
Neutral Pronators should look for a running shoe with a semi curved shape. Stability shoes usually offer a blend of cushioning and support that is beneficial to people with medium arch and pronation.
Shoe Styles on the Human Foot
The human feet of females are far more likely to have problems. For starters, many females are extremely often putting high heels on. The urgent problem with having high heeled shoes is they are usually narrow, and this can lead to big trouble if whatever female feet shoes are too chubby, large or wide for these heels to fit them. Secondly, high heeled shoes are worn for fashion almost everywhere worldwide. High heels oftentimes cause foot deformities and other problems by misshaping the female feet on which the high heels are very often put. Additional problems involving the feet are often tied to high heeled shoes, such as having severe discomfort, wobbling, squished toes and abnormality or deformed feet for later years.
Thirdly, having flip flops are another matter. When humans' feet are accompanied using flip flops, their thongs have to be gripped too often and at very many times. And many podiatrists are advising against having flip flops for different reasons. Flip flops are contributors to other medical problems involving human feet and causing whatever feet are inside them to become uncomfortable.
Fourthly, having shoes that are insignificant in width or too narrow can cause problems involving feet wearing the shoes-bunions, malformation of the feet, hammertoes and claw toe, etcetera. Many people are, unfortunately, having shoes that don't properly fit their feet. Wearing the wrong shoes causes serious problems with the humans' feet.
