Foot supports are widely used by many different health care professions to take care of a number of problems that can affect the feet and lower limb. They are often used when there is a problem with the function or posture of the feet that could be altered to fix the posture or biomechanics. It is widely believed that if the foot is out of alignment an entire variety of problems can affect the feet and lower limb. Not everyone needs foot orthotics, so the choice as to if they ought to be used will be based on the type of the foot and leg problem and the connection of the foot posture to the symptoms.
There are almost as many different types of foot orthoses as there are feet. The options are countless. It is easy to buy a foot insert over-the-counter from many different types of stores and it is pretty much reliant on luck if what you purchase may be the right one for your foot shape and the character of the condition which you have. Many clinicians do prescribe these types of mass produced products for the simple easy to manage foot conditions. However, if the foot structure and the nature of the biomechanics is more complex, then a custom made foot orthotic is generally needed.
The way a professional decides which sort to use is often dependent on a thorough clinical evaluation considering the structure of the feet and the characteristics of the problem. Even unsurprisingly straightforward choices for instance exactly how firm the foot supports should be is complex. Those who need foot supports often prefer the softer ones as they are more comfortable, but the flexible it is, the more likely that it is not going to help. The clinical examination, known as the Supination Resistance, is frequently helpful to attempt to work out how rigid a foot orthotic is needed to work to affect the foot. If you need foot orthoses, then it's probably better to get looked at by a skilled specialist.
