Abstract:
An orthotic insert for removable placement in a shoe having an insole and a heel counter, said orthotic insert comprising:a substantially rigid plate member for engaging a plantar surface of a foot and having a heel end and a forefoot portion, said forefoot portion extending forwardly to at least proximal a metatarsal head area of said foot and having a distal medial portion for engaging said insole substantially along a transverse plane of said shoe; and a heel post having an upper end mounted to said heel end of said plate member and a lower end extending downwardly therefrom, said lower end of said heel post comprising: a generally planar lateral bottom surface that extends upwardly and laterally from said transverse plane, at a predetermined angle for engaging said insole so as to provide angular placement and limit pivoting motion of said heel post in a lateral direction; and a medial bottom surface that extends generally upwardly and medially from said transverse plane for freely interfitting with said insole and heel counter so as to avoid limiting pivoting motion of said heel post in a medial direction; so that said lateral bottom surface of said heel post engages said insole so as to arrest pivoting motion of said orthotic insert in said lateral direction as weight is borne on a lateral side of said foot at heel strike, and said distal medial portion of said plate member engages said insole so as to arrest pivoting motion of said orthotic insert in said medial direction as weight is shifted to a medial side of said foot as said foot progresses through a gait cycle.
