Sandal having an ethylene-vinyl acetate sock lining and the method for producing the sandal

Abstract

A sandal having an ethylene-vinyl acetate (EVA) sock lining in accordance with the present invention is characterized by using an EVA sock lining having excellent resiliency to replace a middle sole in a conventional sandal. Moreover, the EVA sock lining is subjected to thermal conditioning to form a smooth and delicate top face to replace and obviate the necessity of an insole lining. Thereby, structure and manufacturing processes of the sandal are simplified.

What is claimed is:  
     
         1 . A sandal having an ethylene-vinyl acetate (EVA) sock lining comprising: 
 an EVA sock lining ( 10 ) having an outer surface ( 12 ) with a bottom face, a top face and an outer edge;    an outsole ( 20 ) made of durable material attached to the bottom face of the EVA sock lining ( 10 ); and    at least one strap ( 15 ) attached to the EVA sock lining ( 10 ) through the top face;    wherein the top face and outer edge of the EVA sock lining ( 10 ) are subjected to thermal conditioning to form a smooth and delicate surface to abut a person's foot.    
     
     
         2 . The sandal as claimed in  claim 1 , wherein the EVA sock lining ( 10 ) further comprises multiple toe detents ( 16 ) and a heel detent ( 18 ) defined in the top face of the EVA sock lining ( 10 ).  
     
     
         3 . The sandal as claimed in  claim 1 , wherein the at least one strap ( 15 ) is a Y-shaped thong strap.  
     
     
         4 . The sandal as claimed in  claim 2 , wherein the at least one strap ( 15 ) is a Y-shaped thong strap.  
     
     
         5 . A method for producing the sandal having an EVA sock lining in  claim 1 , the method comprising: 
 cutting an EVA block into a foot-shaped EVA sock lining;    thermal conditioning the top face and outer edge of the EVA sock lining;    attaching at least one strap to the foot-shaped EVA sock lining;    obtaining an outsole; and    attaching the outsole to foot-shaped the EVA sock lining to complete the sandal.    
     
     
         6 . The method as claimed in  claim 5 , where the thermal conditioning is performed at 120° C. and 6 kg/cm 2 .
