An orthotic insert adapted to be placed within a shoe having an insole. The orthotic insert has a relatively rigid, resilient base member having a heel portion and an arch portion. The upper surface of the base member is contoured to fit the plantar surface of a person's foot, so as to position the foot in a generally desired angular orientation. At least one curvilinear ridge is formed on the lower surface of the base member, and extends continuously around the rearward end of the heel portion and along the arch portion on both sides of the longitudinal axis of the orthotic insert. The ridge has a sharp lower edge which projects downwardly from the lower surface of the base member for supporting the heel seat in the heel section above the insole when the orthotic insert is placed within the shoe. The lower edge of the ridge is adapted to have material incrementally removed therefrom so that the angular orientation of the foot can be adjusted to suit an individual person. The sharp lower edge of the ridge penetrates into the upper surface of the insole to maintain the insert in position, when the person's weight is applied to the upper surface of the orthotic insert.
