The model was simulated using a load that represents full-weight-bearing and applying traction force to the related tendons that represents the dynamic stabilizer for the ankle (A). Applying force to the sole to simulate plantar support for the medial longitudinal arch (B). The red area is the plantar support area (C).

Results of the validation process.
The values correspond to the difference between the measured distance from each point to the ground, under two different conditions: No weight-bearing and full weight-bearing.
