Corrective orthopedic insole

Abstract

A corrective orthopedic device aimed at preventing excessive pronation, specifically designed for children between the ages of 3 and 16, as well as for adults with flexible flat feet. It features an array of components including a deep heel cup, a substantially elongated medial arch support, and a variably angled medial wedge extending to the ball of the foot. The wedge comes in different levels of correction, such as 3 mm, 6 mm, or 9 mm, with the intent of fostering proper arch support and encouraging better alignment in the sub-talar and ankle joints, which in turn improves overall lower body joint posture. The extended medial or varus wedge starts from the heel and extends to the first metatarsophalangeal (1st MTP) joint, aligning both the rear, midfoot and proximal forefoot in a corrective position. Additional features include a high medial flange and a full-length cushioned top cover for enhanced comfort.

What is claimed is: 
     
         1 . A corrective orthopedic device for a foot composed of multiple supportive and corrective components comprising:
 a. a rigid thermoplastic shell extending from a heel to a ball of the foot or proximal to metatarsal heads of the foot, comprising a rearfoot portion, a midfoot portion, and a forefoot portion having a shell-edge, wherein the rearfoot portion comprising a concave deep heel cup that extends in a semi-circumferential manner around the heel and configured to support the heel in a neutral position;   the midfoot portion extends between the rearfoot portion and the forefoot portion having a sloped-longitudinal-arch portion to support a medial longitudinal arch of the foot;   b. a plantar portion extending substantially along a length of the rigid thermoplastic shell and merges upwardly on its sides to create a soft medial flange and a lateral flange;   c. a neutral arch fill affixed to the thermoplastic shell having an initial thickness and a first length, to obtain a flat surface for a medial corrective wedge portion to provide stability to the heel, wherein
 the medial corrective wedge portion secured underneath the neutral arch fill that extends from the heel to the forefoot portion and passing beyond the shell-edge of the thermoplastic shell in a predefined degree of correction, and wherein the medial corrective wedge portion is configured to extend to a first metatarsal-phalangeal (MTP) joint and is configured to create a medial arch alignment and align subtalar, midtarsal, tarsometatarsal and metatarsal-phalangeal joints to improve lower body joint posture; 
 the medial corrective wedge portion having a second thickness and a second length comprising a layer of angled wedge material configured to extend from the rearfoot portion to the first metatarsal-phalangeal (MTP) in the forefoot portion configured to extend further or past the shell-edge of the thermoplastic shell and angles the rearfoot, midfoot and forefoot portions, 
 whereby the corrective orthopedic device improves ankle alignment, thereby limiting or preventing hyperpronation in children and adults. 
   
     
     
         2 . The orthopedic device of  claim 1 , wherein the plantar portion has a cushioned top cover. 
     
     
         3 . The orthopedic device of  claim 1 , wherein the heel cup has a depth of 20 mm to 35 mm measured from a center portion of the heel cup. 
     
     
         4 . The orthopedic device of  claim 1 , wherein the soft medial flange is configured to extend to the first metatarsal-phalangeal joint from a distal medial calcaneus configured to contain a medial soft tissue splay that occurs with a flat foot type. 
     
     
         5 . The orthopedic device of  claim 1 , wherein the lateral flange configured to extend from a distal lateral calcaneus to a fifth metatarsal base configured to support a lateral arch of the foot. 
     
     
         6 . The orthopedic device of  claim 2 , wherein the soft medial flange has a height of approximately 40-50 mm including the top cover. 
     
     
         7 . The orthopedic device of  claim 2 , wherein the lateral flange has a height of approximately 30-40 mm including the top cover. 
     
     
         8 . The orthopedic device of  claim 1 , wherein the medial corrective wedge portion is configured to extend to the ball of the foot and extend further or past the shell-edge of the thermoplastic shell in the predefined degree of correction. 
     
     
         9 . The orthopedic device of  claim 8 , wherein the predefined degree of correction is between 1.5 mm to 9 mm, preferably 3 mm, 6 mm or 9 mm for user compliance. 
     
     
         10 . The orthopedic device of  claim 1 , wherein the device is constructed from a rigid and durable shell material and wherein the rigid and durable shell material has a maximum thickness between 1.5-4 mm and terminates before the metatarsal heads or ball of the foot. 
     
     
         11 . The orthopedic device of  claim 10 , wherein the rigid and durable shell material is constructed from a thermoplastic shell material that is heat molded to maintain a fixed contour. 
     
     
         12 . The orthopedic device of  claim 1 , wherein the height of the neutral arch fill creates a neutral plantar surface for ankle stability and medial corrective wedge portion addition. 
     
     
         13 . The orthopedic device of  claim 1 , wherein the medial corrective wedge portion and the arch fill are combined as one unit to build the orthopedic device. 
     
     
         14 . The orthopedic device of  claim 1 , wherein the orthopedic device is constructed from the group of materials consisting of polymeric materials, foam, rubber, thermoplastic and cork. 
     
     
         15 . The orthopedic device of  claim 1 , wherein the medial corrective wedge portion is constructed from the group of materials consisting of polymeric materials, EVA, foam, polyurethane, thermoplastic and cork. 
     
     
         16 . (canceled) 
     
     
         17 . The orthopedic device of  claim 1 , wherein the arch fill is constructed from the group of materials consisting of polymeric materials, EVA, foam, polyurethane, thermoplastic and cork.
