Insole

Abstract

An insole inclusive of a hooked pad has an upper layer and a lower layer which meet and define a closed space for containing a gas flowing therein. The hooked pad is defined and divided into a bottom portion, long end portion, and short end portion. The bottom portion connects with the long end portion and the short end portion, with the bottom portion corresponding in position to a heel, the long end portion corresponding in position to the medial longitudinal arch, and the short end portion corresponding in position to the lateral longitudinal arch. Due to its special structure, the insole provides sufficient support, renders walking or running smooth, gives comfort to the foot, makes lengthy standing less tiring, has a long service life, and incurs low production costs.

What is claimed is: 
     
         1 . An insole, comprising:
 a hooked pad comprising an upper layer and a lower layer,   wherein the upper layer and the lower layer meet and define a closed space for containing a gas which flows therein, and the hooked pad is defined and divided into a bottom portion, a long end portion, and a short end portion, with the bottom portion being connected to the long end portion and the short end portion, the bottom portion corresponding in position to a heel, the long end portion corresponding in position to a medial longitudinal arch, and the short end portion corresponding in position to a lateral longitudinal arch.   
     
     
         2 . The insole of  claim 1 , further comprising a lining disposed in the hooked pad. 
     
     
         3 . The insole of  claim 2 , wherein the lining is made of memory foam. 
     
     
         4 . The insole of  claim 1 , further comprising an anti-skid plate disposed at a pit of the hooked pad and connected to the lower layer to the bottom portion, the short end portion, and the long end portion. 
     
     
         5 . The insole of  claim 4 , wherein the anti-skid plate extends from a top of the short end portion to a middle of the long end portion. 
     
     
         6 . The insole of  claim 4 , wherein the anti-skid plate and the lower layer are formed integrally. 
     
     
         7 . The insole of  claim 1 , wherein the long end portion is crescent-shaped. 
     
     
         8 . The insole of  claim 1 , further comprising a transverse arch pad formed integrally with the long end portion. 
     
     
         9 . The insole of  claim 4 , further comprising a transverse arch pad formed integrally with the long end portion. 
     
     
         10 . The insole of  claim 5 , further comprising a transverse arch pad formed integrally with the long end portion. 
     
     
         11 . The insole of  claim 6 , further comprising a transverse arch pad formed integrally with the long end portion. 
     
     
         12 . The insole of  claim 7 , further comprising a transverse arch pad formed integrally with the long end portion. 
     
     
         13 . The insole of  claim 8 , wherein the transverse arch pad is teardrop-shaped. 
     
     
         14 . The insole of  claim 9 , wherein the transverse arch pad is teardrop-shaped. 
     
     
         15 . The insole of  claim 11 , wherein the transverse arch pad is teardrop-shaped. 
     
     
         16 . The insole of  claim 12 , wherein the transverse arch pad is teardrop-shaped. 
     
     
         17 . The insole of  claim 2 , further comprising a transverse arch pad formed integrally with the long end portion. 
     
     
         18 . The insole of  claim 3 , further comprising a transverse arch pad formed integrally with the long end portion. 
     
     
         19 . The insole of  claim 17 , wherein the transverse arch pad is teardrop-shaped. 
     
     
         20 . The insole of  claim 18 , wherein the transverse arch pad is teardrop-shaped.
