1. 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,
wherein the bearing regions comprise an anterior bearing region adapted to lie under the toes of the foot, an intermediate bearing region adapted to lie under the metatarsal heads of the foot, a posterior bearing region intended to lie under the heel of the foot, and an external bearing region intended to lie under the antero-external portion of the calcaneum, under the cuboid and under the fifth metatarsal of the foot.
