Poron material applied to the dorsal surface of the orthotic shell and covers the entire heel cup to cushion the heel.

A wedge-shaped pad that is placed plantar to the cuboid bone on the dorsal surface of the orthotic shell. This Poron pad raises the medial border of the cuboid relative

A Poron pad that is plantar and medial to the longitudinal arch and gives extra support and padding to medial arch area. The pad is applied to the dorsal surface

A dome-shaped Poron pad placed in the metatarsal interspace between the metatarsal heads. It starts at the proximal third of the metatarsal shafts and ends at the metatarsal heads. The

A piece of Poron, usually 3mm thickness, added to the distal edge of the orthosis shell and covers the distal 15% of the orthotic shell. It is designed to transfer

Tear-shaped modification added to the top of the orthosis under a topcover. Made of Poron, it begins at midshaft of the metatarsals and terminates just proximal to the heads of

Any non-rigid material added to the orthosis extending its length beyond the metatarsal heads. Topcover to the sulcus or toes must be present to apply the extension.

Firm EVA material added to the inferior surface of the orthotic heel post to elevate the heel relative to the supporting surface. Rearfoot post must be present to apply lift.

Medium or firm density EVA added under the arch area of the orthotic plate. The EVA fill increases the rigidity of the orthosis by preventing arch collapse. It also creates

A spot grind that goes all the way through the polypropylene, creating a hole in the heel of the orthosis. Allows the orthosis to sit very low in the shoe.
