Anti-Slippery Footwear

Abstract

An anti-slippery footwear includes a sock, an insole, and an attaching structure formed on the attaching surfaces of the sock and insole. The attaching structure has a first attaching portion and a second attaching portion to provide anti-slippery effect while being attached with each other. At least one of the attaching surfaces of the sock and the insole has a recessed portion to accommodate at least one of the first and second attaching portions therein. The joining portions of the attaching structures are slightly lower than the attaching surface of the sock or the insole, such that when the individual wearing the sock is trying to put on a shoe that has the insole, the first and second attaching structures will not attach with each other before the shoe is properly worn by the individual. Instead, the first and second attaching structures will attach to each other only after the shoe is properly worn and a downward pressure is applied thereto.

1 . An anti-slippery footwear, comprising:
 an insole having a first attaching surface;   a sock having a second attaching surface; and   an attaching structure including a first attaching portion formed on the first attaching surface and a second attaching portion formed on the second attaching surface, wherein at least one of the first and the second attaching portion is recessed from a corresponding attaching surface, such that the first and second attaching portion are removably attached together only when being pressed against each other.   
     
     
         2 . The footwear of  claim 1 , wherein the recessed attaching portions include a plurality of holes or stripes and attaching materials formed therein. 
     
     
         3 . The footwear of  claim 2 , wherein the attaching materials are integrally formed with the insole or sock. 
     
     
         4 . The footwear of  claim 1 , wherein the attaching structure includes Velcro. 
     
     
         5 . The footwear of  claim 1 , wherein the insole is fabricated from foam. 
     
     
         6 . The footwear of  claim 1 , wherein at least one of the first or the second attaching portions includes an attaching material formed on the corresponding attaching surface and a perforated covering sheet partially covering the attaching material. 
     
     
         7 . The footwear of  claim 6 , wherein the covering sheet is fabricated from thermal plastic material, thermoplastic elastomer compound, EVA or foam. 
     
     
         8 . The footwear of  claim 7 , wherein the thermal plastic material includes PE, PP, PVC, PU, PC, PET. 
     
     
         9 . The footwear of  claim 7 , wherein the thermoplastic elastomer compound includes, TPU, TPE, TPR. 
     
     
         10 . A sock, comprising:
 a bottom surface having at least a recessed portion; and   an attaching structure formed within the recessed portion to be removably attachable to a corresponding attaching structure formed on an insole or on an interior bottom surface of a shoe.   
     
     
         11 . The sock of  claim 10 , wherein the recessed portion includes a plurality of holes or stripes and attaching materials formed therein. 
     
     
         12 . The sock of  claim 10 , wherein the attaching structure includes Velcro. 
     
     
         13 . The sock of  claim 10 , wherein the attaching structure includes an attaching material formed on the bottom surface and a perforated covering sheet partially covering the attaching material. 
     
     
         14 . The sock of  claim 13 , wherein the covering sheet is fabricated from thermal plastic material, thermoplastic elastomer compound, EVA or foam. 
     
     
         15 . The sock of  claim 14 , wherein the thermal plastic material includes PE, PP, PVC, PU, PC, PET. 
     
     
         16 . The sock of  claim 14 , wherein the thermoplastic elastomer compound includes, TPU, TPE, TPR. 
     
     
         17 . An insole, comprising:
 a top surface having at least a recessed portion; and   an attaching structure formed within the recessed portion to be removably attachable to a corresponding attaching structure formed on a bottom surface of a sock.   
     
     
         18 . The insole of  claim 17 , wherein the recessed portion includes a plurality of holes or stripes and attaching materials formed therein. 
     
     
         19 . The insole of  claim 17 , wherein the attaching structure includes Velcro. 
     
     
         20 . The insole of  claim 17 , wherein the attaching structure includes an attaching material formed on the corresponding attaching surface and a perforated covering sheet partially covering the attaching material. 
     
     
         21 . The insole of  claim 20 , wherein the covering sheet is fabricated from thermal plastic material, thermoplastic elastomer compound, EVA or foam. 
     
     
         22 . The insole of  claim 21 , wherein the thermal plastic material includes PE, PP, PVC, PU, PC, PET. 
     
     
         23 . The insole of  claim 21 , wherein the thermoplastic elastomer compound includes, TPU, TPE, TPR.
