Thermoplastic printed film innersole for shoes

Abstract

The present invention relates generally to a printed film innersole (PFI) and a process for making the same. The present invention provides to a PFI and a process for the construction of an innersole for post-insertion into a shoe that can have significant design details added to the bottom surfaces.

1 . An innersole comprising: 
 a) a first layer made of a printed thermoformable film; and    b) a second layer made of a one or more cast cushioning foam materials    wherein the second layer is positioned beneath and is distinct from the first layer and the first and second layers have planes being directly adjacent.    
     
     
         2 . The innersole of  claim 1 , wherein the printed thermoformable film is a thermoplastic urethane film.  
     
     
         3 . The innersole according to  claim 1 , further comprising a fabric layer contacted with the first layer made of the printed thermoformable film wherein the fabric layer is positioned on top of the printed thermoformable film.  
     
     
         4 . A shoe containing the innersole of  claim 1 .  
     
     
         5 . A process of making an innersole comprising the steps of: 
 (a) providing a thermoformable film;    (b) printing at least one design element onto the thermoformable film to yield a printed thermoformable film;    (c) forming the printed thermoformable film into a shell; and    (d) casting a cast cushioning foam material directly into the shell.    
     
     
         6 . The process according to  claim 5 , wherein the thermoformable film is a thermoplastic urethane film.
