4. Forefoot Lateral Posting
FDI standard orthotics have been designed with an integrated minimal forefoot lateral posting.
This design feature, especially when combined with a first ray recess, assists in plantar flexion of the first ray. This may provide additional stability to the lateral column of the foot, supporting the locking of the midtarsal joint, thereby facilitating transfer of weight for forward propulsion to occur.
If abnormities occur during this phase of the gait cycle the foot may become unstable causing disruption of the calcaneocubiod joint and possibly predisposing to injuries
