When the foot flattens excessively it can trigger an inward rotation in the lower leg bone, the tibia, causing the knees to point toward each other. Of course the upper leg bone will likely follow along, causing increased or altered movement at the hip. So, ultimately excessive or increased movement of the foot into a flattened position can cause pain all the way up the leg to the hip and lower back. Painful flat feet in children may be caused by a condition called tarsal coalition. In tarsal coalition, two or more of the bones in the foot fuse together. This limits motion and often leads to a flat foot. These supports and insoles are available in a variety of forms and sizes; depend on the type of your footwear. Below are some types of arch supports that are used hugely by flat footed people. Sports arch insoles are good for high impact sports as it provides cushion to heel and better shock absorption. These supports are particularly designed for runners, skaters, soccer players and other sports players who need to run throughout the game. These insoles are designed to get better motion control. then waiting for the insole to be completed can take months or, in some cases, well up to a year. Not to In children where flat foot is common, it is caused by the fact that the arch is not yet fully developed. Also, the presence of baby fat can mask the underdeveloped arches which give the impression of flat footedness. However, it will gradually disappear as the child learns to walk and grow from childhood to adulthood. The anatomy of foot is extremely complicated for it consists of bones, ligaments, muscles and tendons. Ligaments are soft tissues that serve as a junction between two bones. On the other hand, tendons join the muscles with the bones. The ligaments and tendons are made up of fibers which are known as collagen Plantar fasciitis and heel spurs - The Achilles tendon becomes shorter and pulls up on the heel of a person with flat feet , causing the arch to flatten and the foot to become longer. Thus, the plantar fascia (tight band of muscle under the foot arch) becomes abnormally stretched, which can lead to pain in the heel bone (plantar fasciitis) and heel spurs. Low back pain - This usually occurs due to strain on the sciatic nerve. This nerve links the lower back to the foot via the leg. The strain is typically caused by repeated shock from running and over-pronation. Flat feet means the inner arch is flat The sole of your foot completely touches the ground when you stand up. This is a common condition and one that can cause pain and discomfort in the feet You can find insoles to wear in your shoes to help with arch support. The insoles have extra support for the arch of your foot to ease pain. The insole puts your foot in a more supported position. If you have flat feet, your feet do not have a normal arch when standing, possibly causing pain when you do extensive physical activity.
