Adaptable orthopedic insoles

Abstract

An orthopedic insole consists of a hollow foothold having flexible walls and containing granular filling. The upper surface of the orthopedic insole is typically molded to conform the anatomical features of a regular human foot. The granular filling contained in the lumen of the foothold and a rigid segment of its bottom wall provide for adapting the curvature angles of the top surface of the foothold to a specific pattern of the foot of a user. A user can typically make a selection from a variety of ready-made insoles having standard sizes which suit his needs. The adaptable orthopedic insoles of the invention are accommodated to common shoes and sandals, boots that are suitable for heavy work, walking, running, and or fashionable or mode shoes.

1 . An adaptable orthopedic insole for footwear comprising
 a hollow foothold having a medial arc support, a tarsal support, a bottom wall and sidewalls;   a rigid plate embedded in a segment of said bottom wall;   a granular filling disposed in a lumen of said foothold, and   wherein at least one wall of said foothold is flexible, and wherein at least one pore is located at a sidewall of said hollow foothold, and wherein the size of said at least one pore is somewhat smaller than the size of any grain of said granular filling.   
   
   
       2 . An adaptable orthopedic insole such as in  claim 1 , wherein said foothold is covered. 
   
   
       3 . An adaptable orthopedic insole such as in  claim 1 , wherein said foothold is manufactured in standard sizes and shapes. 
   
   
       4 . An adaptable orthopaedic insole such as in  claim 1 , wherein the length of said insole is shorter than the length of said footwear. 
   
   
       5 . A method for manufacturing an adaptable orthopedic insole comprising:
 providing mold for standard orthopaedic insole;   injecting a moldable material to said mold;   blow molding said injected material;   releasing said blown injected material from said mold;   filling said blown injected material with granular material;   sealing area of said injection;   covering the upper face of said blown injected material with a material selected from a group consisting of fabric, leather, neoprene, nylon, similar plastic resins or any combination thereof, and   attaching a rigid plate in bottom face of sad blown injected material.   
   
   
       6 . A method for manufacturing an adaptable orthopaedic insole as in  claim 5 , further comprising air vents which are smaller than said grains of the filling located along side walls of said blown injected material.
