Open shoe comprising a textile layer and means of fixation

Abstract

An open shoe including a textile layer shaped to fit on the sole of the open shoe, the textile layer and the open shoe comprising means able to cooperate together in such a manner that the textile layer is attachable and removable relatively to the sole of the open shoe. When the textile layer is attached to the sole, at least a portion of the textile layer is disposed between the open shoe and the skin of the foot.

 at least one first fixing means, the textile layer comprising at least one second fixing means, the at least one first fixing means and the at least one second fixing means being able to cooperate together to removably attach the textile layer to the sole,   wherein the at least one first fixing means comprises a cavity inside the sole,   and wherein the at least one second fixing means comprises a protrusion, said protrusion and said cavity being complementary shaped, said protrusion extending from a bottom surface of said textile layer or from a lateral surface of said textile layer.   
     
     
         2 . The open shoe of  claim 1 , wherein the at least one first fixing means furthermore comprises an opening on an upper surface or on a lateral surface of the sole, said opening being less wide than the cavity's maximum width, said opening linking the cavity to said upper surface or said lateral surface of the sole. 
     
     
         3 . The open shoe of  claim 1 , wherein the at least one first fixing means comprises a first rear fixing means disposed on a heel portion of the sole and a first front fixing means disposed on a toe portion of the sole. 
     
     
         4 . The open shoe of  claim 1 , wherein at least one of said at least one first fixing means is disposed substantially transversally relatively to the sole. 
     
     
         5 . The open shoe of  claim 1 , wherein the at least one first fixing means comprises a first arch fixing means disposed on an arch portion of the sole. 
     
     
         6 . The open shoe of  claim 1 , wherein the at least one first fixing means disposed on the arch portion of the sole is disposed substantially longitudinally relatively to the sole. 
     
     
         7 . The open shoe of  claim 1 , wherein the at least one second fixing means comprises at least one second rear fixing means disposed on a heel portion of the bottom surface of the textile layer or on the lateral surface of the heel portion of the textile layer, and at least one second front fixing means disposed on a toe portion of the bottom surface of the textile layer or on the lateral surface of the toe portion of the textile layer. 
     
     
         8 . The open shoe of  claim 1 , wherein the at least one second fixing means comprises a second arch fixing means disposed on an arch portion of the bottom surface of the textile layer. 
     
     
         9 . The open shoe of  claim 1 , wherein the at least one second fixing means is in a material selected from polymers, thermoplastics, polypropylene, polyethylene, polystyrene, polyvinyl chloride, polyamide, resins, silicones or a combination thereof. 
     
     
         10 . The open shoe of  claim 1 , wherein the sole is in a material selected from polyurethane, elastomers, rubber, rubber foam, ethylene-vinyl acetate, ethylene-vinyl acetate foam, leather, hide or a combination thereof. 
     
     
         11 . The open shoe of  claim 1 , wherein the textile layer is in a material selected from textile fibers, preferentially cotton, silk, wool, polyester, nylon or acrylic, or a combination thereof. 
     
     
         12 . The open shoe of  claim 2 , wherein the opening of the at least one fixing means is surrounded by a first material, said first material being harder than a second material constituting the sole. 
     
     
         13 . The open shoe of  claim 1 , wherein the at least one first fixing means is in a first material, said first material being harder than a second material constituting the sole, and said first material being snug fitted or snap fitted inside the sole. 
     
     
         14 . The open shoe of  claim 1 , wherein the textile layer furthermore comprises an orthopedic sole. 
     
     
         15 . The open shoe of  claim 1  furthermore comprising a toecap, wherein the toecap comprises at least one second fixing means. 
     
     
         16 . The open shoe of  claim 15 , wherein at least two first fixing means are present in the toe part of the sole. 
     
     
         17 . The open shoe of  claim 1 , wherein the cavity is substantially a cylinder, a cone or a prism. 
     
     
         18 . The open shoe of  claim 1 , wherein each second fixing means furthermore comprises a head part that is woven, sewn, glued, stitched, pressed thermally, ultrasonically welded or bound to the textile layer on the bottom surface of the textile layer or on the lateral surface of the textile layer. 
     
     
         19 . The open shoe of  claim 1 , wherein each second fixing means is a rod disposed inside a fold on the lower surface of the textile layer or inside a fold on the lateral surface of the textile layer. 
     
     
         20 . A method to make an open shoe ( 1 ) able to receive a removable textile layer ( 21 ), said method comprising the steps of:
 a) Providing an open shoe ( 1 ) with a sole ( 11 ),   b) Forming a first fixing means ( 12 ) on the open shoe ( 1 ) by forming at least one cavity ( 13 ) inside the sole ( 11 ) of the open shoe ( 1 ) and by forming at least one opening ( 14 ) between the at least one cavity ( 13 ) and an upper surface ( 11   a ) of the sole ( 11 ) of the open shoe ( 1 ),   c) Providing a textile layer ( 21 ) with at least one second fixing means ( 22 ) attached to the textile layer ( 11 ) on its lower surface or on one edge of said textile layer ( 11 ), said second fixing means ( 22 ) comprising a protrusion ( 23 ) able to cooperate with the at least one cavity ( 13 ) of the first fixing means ( 12 ).
