Abstract
A plantar insole has bearing areas (6, 7, 8, 9) of the main surface which are provided with a rigidity or hardness which are less with respect to other areas (10-13) of the main surface. These areas (6-9) are arranged under the major bearing areas of a foot, i.e. under toes, under the metatarsal heads, under the heel and under the external bearing area of the foot, making it possible to attain a compromise between the necessity of an impact absorption and stabilization of the foot in a shoe. The insole may be adapted to any type of footwear.

1-10. (canceled)
Plantar insole for use in footwear between an insole of the footwear and the plantar surface of a foot, the plantar insole being delimited by a main upper surface adapted to be in contact with the plantar surface of the foot, a main lower surface adapted to be in contact with the footwear insole and a peripheral contour conformed to extend beyond the plantar surface of the foot and to fit inside the interior contour of the footwear, the plantar insole having at least two different stiffnesses or hardnesses as a function of the main surface regions concerned, wherein:
- the insole has, on its main surface, bearing regions disposed to lie under each of the major bearing areas of the foot,
- the bearing regions have a relative stiffness or hardness lower than that of the other regions of the main surface, and
- the bearing regions are delimited by a contour flanking said major bearing regions of the foot.
