Method for manufacturing waterproof shoe

Abstract

A method is used for manufacturing a waterproof shoe having an enclosure to be secured or stitched to a shell, and a midsole and an outsole. The shell includes a widely opened bottom opening formed by the bottom peripheral portion of the shell for allowing the enclosure to be easily and quickly stitched to the shell. One or more flexible flaps are secured to the bottom peripheral portion of the shell. A shoe last and one or more insulating liners may also be easily engaged into the shell. The flaps may be solidly folded to engage with the shoe last or the midsole.

I claim:  
     
         1 . A method for manufacturing a waterproof shoe including a shell having a bottom peripheral portion, an enclosure having a bottom peripheral portion, a midsole and an outsole, said method comprising: 
 forming an opening in a bottom portion of said shell, said opening being defined by said bottom peripheral portion of said shell,    securing at least one flap to said bottom peripheral portion of said shell,    securing said bottom peripheral portion of said enclosure to said shell with stitches,    inserting a shoe last into said shell,    engaging a midsole onto said shoe last,    forcing said at least one flap inward of said shell,    securing said at least one flap to said midsole, and    forming said outsole onto said shell.    
     
     
         2 . The method according to    claim 1    further comprising applying at least one waterproof layer onto said stitches to insulate said stitches.
