Foot supports are commonly used by many different professions to deal with a variety of conditions that could affect the feet and lower limb. They are often indicated if you have an issue with the biomechanics or alignment of the feet which might be altered to improve alignment or biomechanics. It is commonly thought that when the foot is out of position an entire variety of conditions may affect the feet and lower limb. Not every person needs foot orthotics, so the determination as to when they should be used will be based on the type of the foot and leg problem and the connection of the foot alignment to the symptoms.
There are nearly as many different types of foot orthotics as there are feet. The options are endless. It is easy to buy a foot insert over-the-counter at various sorts of stores and it is almost reliant on luck if what you get may be the most suitable one for your foot structure and the character of the problem that you have got. Many doctors do suggest these kind of non-prescription inserts for the simple not difficult to deal with foot symptoms. Having said that, if the foot type and the nature of the biomechanics is more complex, then a custom foot orthotic is normally indicated.
How a professional decides which kind to use is usually dependent on a comprehensive clinical examination looking at the posture of the foot and the characteristics of the symptoms. Even apparently easy decisions for instance just how rigid the foot orthotic should be is complicated. People who need foot insoles generally prefer the less rigid ones since they are more comfortable, but the flexible it is, the more likely that it is not going to work. The clinical examination, named the Supination resistance test, is frequently helpful to try and work out how rigid a foot orthoses is needed to work to affect the foot. If you need foot inserts, then it is probably better to get evaluated by a competent podiatrist.
