Types
of orthotic insoles
There are
different types of orthotics insoles for
different problems. Once such problem that
requires the need for insoles, is over pronation
or flat feet. This is caused when the arch
of a person`s foot has collapsed under weight
bearing and can lead to many other problems.
If you are suffering from flat feet, it may
be wise to see a podiatrist/orthotist for
assessment, evaluation and treatment of the
problem through prescribe custom made orthotics
and insoles.
Custom made
foot orthotics are insoles that are made
to suit the specific requirements needed
to mend the biomechanical problem. Once the
problem has been assessed through a range
of joint motion tests and gait analysis,
an impression and cast will be made of your
foot. This is then passed on to an orthortist
/podiatrist to fabricate a pair of customized
orthotics, with instructions from the orthortist/podiatrist,
which is catered specifically to your foot.
Heat moldable
insoles are also available which is a more
cost friendly way of buying orthotics. Custom
made orthotics can be expensive. Heat moldable
insoles can be manipulated through the use
of applied heat to fine-tuned to your feet.
These can be more comfortable than custom
made insoles but may not provide as much
support in the long term.
Insoles come
under five different types, these are:
 Rigid
insoles - to control movement
Semi-rigid insoles
- for athletes and physical activity, to provide balance and shock absorption
Soft insoles
- to relieve pressure and achieve pain relief
Calibrated (customised)
insoles - to help flexibility, weight and activity levels
Proprioceptive
insoles - provide support by applying a tactile stimulation to the bottom of
the foot. In theory, this tactile stimulation transmits a signal to the cerebellum
(the balance center of the brain). Acting on this signal, the cerebellum initiates
a postural correction affecting the entire body. It neutralises the body to
a more upright balanced gait posture; therefore allowing the body to move in
a more balanced posture.
Orthotic
insoles can be purchased over the counter
as-well without prescription and can be easily
slotted into orthopedic shoes that cater
to the specific used of such devices. However,
commercial/normal shoes may not necessarily
have enough volume to cater to the insoles
