Foot orthotics are frequently used to deal with a variety of foot problems from overpronation and fallen arches to plantar fasciitis and other reasons for heel pain. The research evidence points to them being usually very good at helping most of the disorders as long as they are indicated for that condition. Foot orthoses are often get used to support the foot. However, support of the foot could have nothing to do with the problem that the individual might have. This might lead to them being misused and mistakenly blamed for treatment failures. The other problem is that there are various sorts of foot orthoses as well as within each kind of foot orthotic, there is an pretty much infinite variance in the design features which can be included in them. If even one of those design features is not good for the person, then the prospects of that foot orthotic helping is potentially reduced. That is why the choice of the different designs is actually determined by the experience and expertise of the clinician. The clinician will select the design features in the foot orthotics that are necessary for the individual and if the device needs to be customized for the individual or if a pre-made device which is more affordable foot orthotic may be used.
With regards to custom made orthoses, the podiatrist needs to take a plaster cast or optical scan of the foot held in specific positions for the foot orthotic to be made on. When it comes to the style of the device different elements are evaluated. For example, if the patient has adult acquired flat foot, then something like a MOSI type foot orthotic is required. The MOSI has special modifications to deal with the range of problems that occur in that condition. If the concern is linked to a lack of impact absorption, then the orthotic must be designed to cater to that. The range of options is endless and will depend on the disorder present and the experience of the treating clinician.
