What exactly is an 'Orthotic Insole'?
An 'orthotic insole' is a device designed to restore your natural foot function. Many 'biomechanical' (walking) complaints such as heel pain, knee pain and lower back pain are caused by poor foot function. Orthotic Insoles or shoe insoles re-align the foot and ankle bones to their neutral position, thereby restoring natural foot function. In turn this helps alleviate problems in other parts of the body.
In addition, orthotic insole give a more even weight distribution, taking pressure of sore spots (e.g. the ball of the foot, corns in between toes, bunions etc) and they provide some shock absorption.
