Flexible midfoot orthotic shoe insert

A preformed orthotic for disposition between a shoe and a foot of a user, the orthotic comprising:

• a proximal edge disposed adjacent a heel of a foot of a user;
• a distal edge disposed adjacent a metatarsal head area of the foot;
• a lateral edge disposed adjacent a lateral side of the foot;
• a medial edge disposed adjacent a medial side of the foot;
• wherein the orthotic insert defines a functional support surface which extends between the heel and the metatarsal head area and which does not substantially extend beneath the heel or beneath the metatarsal head area;
• a lateral contour zone disposed on a lateral side of the orthotic insert;
• wherein the lateral contour zone has a thickness adjacent a medial-lateral center line of the orthotic insert which is between about three and thirty percent of a proximal-distal length of the orthotic insert;
• wherein the lateral contour zone tapers towards the proximal edge and the distal edge to a reduced thickness;
• and
• wherein an upper surface of the lateral contour zone slopes upwardly in a medial direction from the lateral edge at an angle of between about one and fifteen degrees;
• and
• a medial contour zone disposed adjacent the lateral contour zone and extending towards a medial side of the orthotic insert;
• wherein the medial contour zone has a thickness which is between about three and thirty percent of the proximal-distal length of the orthotic insert;
• and
• wherein an upper surface of the medial contour zone slopes upwardly in a medial direction at an angle of between about fifteen and forty degrees.
