Which Arch Support Inserts Should You Select?
Generally speaking, there are three different styles of orthotic insoles to choose from when you are about to make a worthwhile investment for the health of your feet. Each of these has varying features, and are used depending on your particular situation.:

1) Custom-made (rigid) orthotics: These orthotic shoe insoles are for individuals with intense biomechanical disorders that are more serious than the general degree of excess pronation that many of us deal with. Custom-made, rigid orthotic insoles must be prescribed by a podiatrist. For example, some people deal with ‘supination’, which is the contrary to pronation. Their feet roll to the outside or 'supinate', and the arch stays high and rigid when hitting the ground. This is known as a high-arched foot or cavus foot, and only affects 5 percent of people. Supinators will require a custom-made orthotic that fixes this type of problem. In addition, people with very large bunions, foot ulcers, foot deformities or completely flat feet should see a foot specialist. After preliminary diagnosis of flat feet, or any of the before mentioned ailments, the podiatrist will select the proper custom-made prescription orthotic. Subsequently, a negative-impression plaster cast of the patient's feet is prepared, and this cast is then sent to an a special laboratory for manufacturing orthotics. Based on this cast, a positive cast is formed by pouring plaster into the negative mold. The result is a precise reproduction of the bottom of the foot. From this copy, the orthotist (orthotics technician) will produce a custom orthotic, providing the needed adjustments, as requested by the podiatrist. The result is a rigid (or semi-rigid) orthotic device. Although these devices are biomechanically correct, many patients find it very difficult getting accustomed to them.

2) Heat-moldable orthotics: Heat-moldable orthotics are a cheaper alternative to the expensive custom orthotics, which often cost hundreds of dollars per pair. They are a standard, off-the-shelf, flexible device made of medium-firm density E.V.A. material. The device then can be heated to slightly change its contour. At times wedges are added for a more customized feel. Heat-moldable orthotics cost around $100 to $140 and are a lot easier to get used to than custom stiff orthotics.

3) Off-the-shelf Orthotic Inserts: Off-the-shelf orthotics are a soft-medium density insole, offered at drug stores, online from specialist e-commerce sites, and also from some physiotherapists and chiropractors. Individuals will get used to these orthotics almost right away, and the cost varies from $30 to $50 per pair. Research proves that for 80% of people suffering from over pronation, a prefabricated insole will provide sufficient support. After a few weeks of insoles will adapt to the wearer’s foot shape, because of their body weight and body heat. The majority of prefabricated orthotic insoles are made of EVA, a pliable but firm substance that supports the foot without damaging the arches. Children and the elderly will in particular benefit from a more pliable type of insole, since they are less tolerant of anything stiff below their feet.

It is always a good idea to receive the advice of a specialist when you are making this type of decision. You want to ensure you are making the most appropriate selection for your particular condition.
