Model P2

Supports the arch of patients suffering from flat and low arch pathologies. Prevents the progression of flat-footedness and tendon deterioration.


  • Highly restrictive orthoses
  • Provides significant ground reaction force (GRF)

The Adult Acquired Flat Foot device is designed to provide the highest level arch support to stave off the progression of flat-footedness and tendon deterioration and reduce the symptomatic pain of arch collapse.

The Adult Acquired Flatfoot device is casted with minimal lowering of the arch to keep the arch elevated to it’s proper positioning.  A rigid polypropylene shell provides support and a medial flange controls pronation.  It is the ideal ortho for stage 1 adult-acquired flat foot or grade I and II posterior tibial tendon dysfunction.  

This device is designed to fit in most shoes with removable sock liners or insoles. It’s finished with an extrinsic crepe rearfoot post, a vinyl top cover, EVA arch filler, and full length Myolite cushioning.

The Adult Acquired Flat Foot device is constructed with a positive model of the patient’s foot and can be modified at the practitioner’s discretion.
