Method and Apparatus for Custom Fitting Footwear

Abstract

A method and apparatus of custom-fitting footwear, the method including receiving a fillable bag insert into footwear and receiving solidifying material into the fillable bag insert. The method further includes continuing to receive the solidifying material until a space between an interior portion of the footwear and a user's footspace is substantially filled.

We claim: 
     
         1 . A method of custom-fitting footwear, the method comprising:
 receiving a fillable bag insert into footwear;   receiving solidifying material into the fillable bag insert; and   continue receiving the solidifying material until a space between an interior portion of the footwear and a user's footspace is substantially filled.   
     
     
         2 . A method of  claim 1 , wherein receiving the solidifying material continues up to a reaching of the user's comfort level. 
     
     
         3 . A method of  claim 1 , wherein footspace includes the space the foot takes up when in the footwear. 
     
     
         4 . A method of  claim 1 , wherein receiving a fillable bag insert into footwear occurs during manufacturing of the footwear. 
     
     
         5 . A method of custom-fitting footwear, the method comprising:
 inserting a fillable bag insert into a footwear space;   coupling a delivery device for a solidifying material to the fillable bag insert;   delivering the solidifying material to the fillable bag insert;   continue delivering the solidifying material to the fillable bag insert until an extra space is substantially filled; and   decoupling the delivery device from the fillable bag insert.   
     
     
         6 . A method of  claim 5 , wherein the solidifying material is polyurethane-solidifying foam. 
     
     
         7 . A method of  claim 5 , wherein the solidifying material is a spray foam. 
     
     
         8 . A method of  claim 5 , wherein the delivery device is a flexible tube, and the delivering the solidifying material to the fillable bag insert is accomplished with a pressurized canister. 
     
     
         9 . A method of  claim 5 , wherein the fillable bag insert has adhesive on a portion of the exterior of the fillable bag insert. 
     
     
         10 . A method of custom-fitting footwear, the method comprising:
 placing a delivery device for a solidifying material into extra space of a footwear;   delivering the solidifying material to the extra space;   continue delivering the solidifying material until the extra space is substantially filled; and   removing the delivery device from the footwear.   
     
     
         11 . A method of  claim 10 , wherein the solidifying material is polyurethane-solidifying foam. 
     
     
         12 . A method of  claim 10 , wherein the solidifying material is spray foam. 
     
     
         13 . A footwear insert comprising:
 a solidifying material delivered to substantially fill an extra space between a footwear interior and a footspace;   wherein the solidifying material solidifies after entry into the extra space.   
     
     
         14 . A footwear insert of  claim 13 , wherein the solidifying material is polyurethane-solidifying foam. 
     
     
         15 . A footwear insert of  claim 13 , wherein the solidifying material cures to a hardness configured to stabilize a foot inside of the footwear. 
     
     
         16 . A footwear insert of  claim 13 , further comprising a fillable bag insert configured to receive the solidifying material. 
     
     
         17 . A footwear insert of  claim 13 , further comprising adhesive placed into the footwear prior to the delivery of the footwear insert so that the footwear insert is assisted in remaining inside the footwear by the adhesive. 
     
     
         18 . A footwear insert comprising:
 a malleable material delivered to substantially fill an extra space between a footwear interior and a footspace;   wherein when two different portions of the material are pressed together the two portions join to form a single portion.   
     
     
         19 . A footwear insert of  claim 18 , wherein the malleable material is a viscoelastic liquid silicone. 
     
     
         20 . A footwear insert system comprising:
 a solidifying material container;   a fillable bag insert configured for placement between a toe portion of a foot and an interior portion of a footwear;   a delivery device configured to direct the solidifying material into the fillable bag insert to reduce an extra space between the toe portion and the interior portion.
