Customized Foot Orthoses With Orthotic Wedges for Plantar Heel Pain

The orthotic wedges with a full length of 3-mm soft foam layer will be provided to each participant under the molded orthoses; the amount of wedge angle will depend on the rearfoot and forefoot angles of the participants. The present study developed 3-degree, 6-degree, and 8-degree wedges for the rearfoot and forefoot. It was made from solid rubber with a cover of thin fabric. There are three sizes for these products which include small (S), medium (M), and large (L) sizes, according to the foot length of participants.

The 3-quarter-length CFO will be made from thermoplastic material (rigid foot orthoses) which consists of four layers i.e. two layers of 0.5-mm polyvinyl chloride (PVC), one layer of 1.5-mm thick fiber to increase strength of foot orthoses in the bottom layers as well as one layer of 1.2-mm genuine leather in the upper layer to increase comfort. It incorporates a heat-molding process to adjust individual foot shape in prone position. The materials will be set within approximately three minutes.
