Definitions

• the present invention relates to a new plantar orthosis or orthopedic sole.
• This sole can be produced in removable form or plantar orthosis or even insole, or not be removable and constitute a bonded insole, or even the upper part of the sole of the shoe. It is usual, in the practice of orthopedics, to create plantar orthoses according to the needs, at least such as the orthopedist determines them, for the person intended to wear the orthosis (s). The result is a handcrafted production practically by unit, and resulting in a high cost. The present invention proposes to remedy these drawbacks.
• the subject of the invention is a plantar orthosis comprising, from front to rear, on a substantially flat area (17), so-called undercapital areas, namely an area (11) for the first metatarsal and an area (12) for the fourth and fifth metatarsals, behind these zones, separated from each other, a retro-capital bar area or retro-capital support (13) said zones having substantially the contours shown on FIG. 1, and reliefs substantially as appearing in FIG. 2.
• the plantar orthosis can optionally comprise, in addition, towards the rear, an internal hemicoupole zone (14) and a zone of external hemicoupole (15), the plantar orthosis ending in a heel ring (16), said zones having the contours shown in FIG.
• the combination of all of these zones results in almost universal character of the plantar orthosis, said zones having respectively the following characteristics, from a horizontal geometric reference plane: - the under-capital zones (11) and (12) have a height of between 0.5 mm and 10 mm and are flat or slightly tilted forward; - the retro-capital bar area (13) has a median bulge behind the different metatarsal heads (with a flat or curved shape in cross section and inclined rearward in longitudinal section), the maximum height of said area being included between 2 to 10 mm, preferably 4 to 5 mm; - Or the retro-capital bar area is replaced by a retro-capital support area located behind the second, third and fourth metatarsal heads, the maximum height of said area being between 2 and 10 mm; - the internal hemicoupole zone (14) is generally convex in a longitudinal plane and follows the internal arch of the foot, and in a

• Exhibit A - anterior limits, (21.22): they correspond to a plantar footprint with digital vacuum a few millimeters in front of the anterior limit of the forefoot footprint, so as to predict the progress of the capiton plantar and metatarsals during the digitigrade phase of the step.
