The foot is a complicated part of the body as there are a lot of small bones which are joined together by so many ligaments and moved by so many muscles. In addition to that we take the bodyweight on the foot and subject it to so many pressures. To make it worse we put the feet inside the artificial environment of footwear. It's because of this that the career of podiatry exists since there is just so much that may go wrong with the feet and connected structures. Foot doctors use a wide range of different interventions to treat conditions of the feet and lower limb.
Foot supports are often used to take care of the wide range of problems that can be wrong with the foot. The objective of foot supports are to alter the posture of the feet in the direction of a more corrected normal position or to reduce the load in structures of the feet which might be leading to symptoms so that they can improve. The foot supports achieve that via having various design characteristics that are supposed to match the foot. A bespoke foot orthoses will do that. However, non-prescription orthotics can do that, often by chance. They might or might not match the feet of the person with them as opposed to a custom made support will. There are many different designs varied, such as the elevation of the mid-foot ( arch ) as well as the amount of shock absorption. There are even designs referred to as Kinetic wedge and Cluffy Wedge.
Occasionally the less costly over-the-counter type supports are better and other times the bespoke ones are more effective. It will all be determined by the nature of the condition, the foot type and structure as well as the advice of a good podiatrist in regards to what is the best alternative. For those who have an issue with your feet and think you need some foot supports, then go to a good physician.
