Abstract:
1. A method of forming a two-part orthotic insert for an article of footwear having a hard shell portion and a soft overlying portion, method steps of forming said hard shell portion comprises, a. locating and marking the centered highest point of the medial longitudinal arch and lateral longitudinal arch position on a patient's foot, b. locating and marking the posterior distal portion of the metatarsal bones positioned on the bottom of a patient's foot, c. locating and marking the first and fifth metatarsal-phalangeal joints on the patient's foot, d. selecting an orthotic blank to be formed under the method, e. positioning a patient's leg and foot in a sitting angular specific position, f. positioning a resilient mat for future engagement with said patient's foot and positioning a silicone sheet thereon, g. heating said selected orthotic blank to a malleable temperature in a heat source, h. positioning said heated orthotic blank on said resilient mat, i. placing a heat shield on said heated orthotic blank, j. positioning the patient's foot on said heat shield and said orthotic blank, k. instructing the patient to extend the toes up to maximize the medial and lateral longitudinal arch if needed, l. applying an upward superior force against the medial and lateral longitudinal arches forming the medial and lateral arches of the foot via the mat and aligned orthotic blank against the underside of a patient's foot deforming said orthotic blank in compliance therewith, m. applying an upward superior force against the medial and lateral portions of the hindfoot forming a customized cup for the heel, n. repositioning said patient's foot to a heel up position, applying downward pressure to the mid and forefoot area of the foot on said orthotic blank, o. removing a custom formed orthotic plate from the patient's foot and cooling, p. repositioning the patient's foot on said cooled custom formed orthotic plate and marking thereon corresponding to said patient's first and fifth metatarsal-phalangeal joint location marking on said foot as set forth in step “c”, q. tracing the patient's foot outline and marking same on said custom formed orthotic plate and interconnecting said transferred first and fifth metatarsal-phalangeal joint marks with a straight line, r. cutting and shaping said marked custom formed orthotic plate in accordance with said outline markings, s. contact transferring of location marks applied to the bottom of the foot corresponding to said distal posterior bottom portions of the first, fifth and a third metatarsal-phalangeal joint from said patient's foot to an upper foot effacing surface of said custom formed orthotic plate, t. selecting, sizing and attaching a transverse arch pad to said custom formed orthotic plate locations as set forth in step “s”, u. securing a releasable fastener to said upper surface of said custom formed orthotic plate in spaced longitudinal relation to said transverse arch pad as set forth in steps “t”.
