You may have your feet scanned, cast or pressed into a foam box for your 3D foot model. Following this your orthotist will modify the model to correct abnormal foot biomechanics, offload painful areas, distribute pressure and increase comfort. Foot orthoses can be made from many different materials, soft to firm foams, rigid to flexible plastics as well as cork and other heat moldable materials. The style and material for your insoles or inserts are based specifically for your requirements.
