Waterproof and breathable footwear resistant to post-treatment

Abstract

A footwear includes an upper and a sole. The upper includes a membrane and at least one outer layer. The membrane is a waterproof and breathable membrane. The membrane is attached to an insole and the membrane is attached to a lower end of the outer layer. The membrane is adhered to the lower end of the outer layer by an anchoring adhesive. The anchoring adhesive is resistant to post treatment and the insole is attached to the sole.

         22 - 25 . (canceled) 
     
     
         26 . The footwear according to  claim 1 , wherein the anchoring adhesive is heat-activated. 
     
     
         27 .- 32 . (canceled) 
     
     
         33 . The footwear according to  claim 1 , wherein the anchoring adhesive is at least one of; epoxies, methyl methacrylates, silicone adhesives, or urethanes. 
     
     
         34 .- 37 . (canceled) 
     
     
         38 . The footwear according to  claim 1 , wherein the anchoring adhesive is a polyurethane, and
 wherein an application temperature of the anchoring adhesive is between 90-160 degrees Celsius.   
     
     
         39 .- 59 . (canceled) 
     
     
         60 . The footwear according to  claim 5 , wherein the stitching attaches a lower end of the membrane to the insole by stitches without perforating the lower end of the outer layer. 
     
     
         61 .- 68 . (canceled) 
     
     
         69 . The footwear according to  claim 1 , wherein the sole is injection molded to the upper. 
     
     
         70 .- 75 . (canceled) 
     
     
         76 . The footwear according to  claim 60 , wherein the lower end of the outer layer is adhered around substantially a total circumference to the lower end of the membrane.
