=> The simplest types of prefabricated FOs are in-shoe pads.
=> Felt forefoot pads are available to relieve metatarsal GIA, sesamoiditis, traumatic, Neuroma, and intractable plantar keratoma (Fig 1.1). These adjust pressure by off-loading adjacent areas and increasing pressure on the pad itself. Thus they are often placed near, but not directly under, the area of pain.
=> Heel pads are designed to relieve pressure and symptoms associated with plantar heel spur syndrome and plantar heel fat pad atrophy (Fig 1.2). They distribute forces over a larger area, thus decreasing pressure under the heel.
=> Flat insoles are used primarily for cushioning the impact during walking and running. These flat, cushioned insoles can also off-load bony prominences and are used to prevent pressure-induced pathologies of the foot – Fig 1.3
=> Contoured cushioned prefabricated insoles are also prevalent and have a wide variety of clinical application for relief of plantar foot pressures, dissipation of impact shock, and enhancement of overall foot comfort. These contoured insoles also function as a softer version of a prefabricated arch support – Fig 1.4
=> Prefabricated, “biomechanical” semirigid foot orthotics have gained popularity over recent years. These devices made from materials commonly used in the fabrication of more expensive custom functional Fos. Prefabricated biomechanical devices contoured to an average shape of a medical and lateral longitudinal arch. In general, these devices lack any heel cup. Sometimes, posting is provided to enhance the rear foot pronation control.
=> The goal of treatment of these devices is to provide more rigid support and motion control than with softer arch supports.
