Arch Support Insole for Shoes

Abstract

An arch support insole includes a basic body made from soft flexible material having a top surface, a heel support portion in form of crescent moon shape and projecting upward from the top surface and a palm support portion in front of the heel support portion. The heel support portion has two distal ends that gradually increase in thickness toward a center area thereof thereby forming a curved surface with an apex at the center area which is spaced from the top surface of the basic body at 5 mm˜9 mm and wherein the palm support portion has an upwardly curved top surface with a topmost point which is spaced from the top surface of the basic body at 1 mm˜6 mm.

What is claimed is: 
     
         1 . An arch support insole comprising:
 one piece integral basic body made from soft flexible material having a top surface, a heel support portion in form of crescent moon shape and projecting upward from said top surface and a palm support portion in front of said heel support portion, wherein said heel support portion has two distal ends that gradually increase in thickness toward a center area thereof thereby forming a curved surface with an apex at said center area which is spaced from said top surface of said basic body at 5 mm˜9 mm and wherein said palm support portion has an upwardly curved top surface with a topmost point which is spaced from said top surface of said basic body at 1 mm˜6 mm.   
     
     
         2 . The arch support insole according to  claim 1 , wherein said basic body defines an imaginary longitudinal axis extending symmetrically through a central portion thereof, said heel support portion having an imaginary radius owing to configuration of the crescent moon shape defining an acute angle ranging 4°˜9° in cooperation with said imaginary longitudinal axis of said basic body. 
     
     
         3 . The arch support insole according to  claim 1 , wherein a profile of said heel support portion is spaced apart from a profile of said palm support portion at 31.8 mm˜35 mm. 
     
     
         4 . The arch support insole according to  claim 2 , wherein a profile of said heel support portion is spaced apart from a profile of said palm support portion at 31.8 mm˜35 mm along said imaginary longitudinal axis. 
     
     
         5 . The arch support insole according to  claim 3 , further comprising a protection layer coated on said top surface of said basic body, thereby covering said heel support portion and said palm support portion.
