AB - Custom-made orthotic insoles are routinely used in the treatment of the diabetic foot to reduce plantar
pressure so as to minimise the risk of neuropathic ulceration. Due to the 3D geometry shape of the foot
and insole, the measurement of the foot-orthosis interface pressure at different plantar regions in relation

After validation, the simulated deformation shows good agreement with the result obtained by image
