Footwear having selectively attachable sockliner

Abstract

Footwear includes a sole, an upper attached to the sole to define a volume for receiving a foot therein, and a sockliner received in the volume and overlying the sole. The sole includes at least one first fastener element formed therein, and the sockliner includes at least one second fastener element formed therein. The second fastener element is adapted for snap-together fastening with the first fastener element for securing the sockliner to the sole.

1 . Footwear comprising a sole, an upper attached to the sole to define a volume for receiving a foot therein, and a sockliner received in the volume and overlying the sole, the sole including at least one first fastener element formed therein, and the sockliner including at least one second fastener element formed therein, the second fastener element being adapted for snap-together fastening with the first fastener element for securing the sockliner to the sole. 
   
   
       2 . Footwear as set forth in  claim 1  wherein the sockliner has a perimeter and the second fastener element is located inward of the perimeter. 
   
   
       3 . Footwear as set forth in  claim 2  wherein there are plural first and second fastener elements, the second fastener elements being located inward of the periphery of the sockliner. 
   
   
       4 . Footwear as set forth in  claim 3  wherein each second fastener element comprises a shaft and a head, the head having a width, each first fastener element including a cavity and an opening allowing access to the cavity, the opening having a width less than the width of the head. 
   
   
       5 . Footwear as set forth in  claim 4  wherein each head is resiliently deformable for allowing the head to pass a corresponding opening and into the cavity. 
   
   
       6 . Footwear as set forth in  claim 1  wherein the second fastener element is selectively unfastenable from the first fastener element to thereby allow the sockliner to be removed from the sole. 
   
   
       7 . Footwear as set forth in  claim 1  wherein the sole is made of EVA. 
   
   
       8 . Footwear as set forth in  claim 7  wherein the sockliner is made of EVA. 
   
   
       9 . Footwear as set forth in  claim 8  wherein the EVA of the sole has a hardness greater than a hardness of the EVA of the sockliner. 
   
   
       10 . Footwear as set forth in  claim 1  wherein the upper and sole are configured to define a clog. 
   
   
       11 . Footwear as set forth in  claim 1  wherein the sockliner has a surface area that is less than the surface area of the sole. 
   
   
       12 . Footwear as set forth in  claim 11  wherein the sole includes a recess sized and shaped for receiving the sockliner. 
   
   
       13 . Footwear comprising:
 an upper shaped to define a volume for receiving a foot therein and having an opening for passage of the foot into the volume;   a sole having the upper attached thereto, the sole having a top surface and a bottom surface, the top surface including a plurality of cavities and openings allowing access to the cavities; and   a sockliner for overlying the top surface of the sole and underlying the foot of the wearer, the sockliner including a plurality of tabs selectively insertable into the cavities of the sole to thereby secure the sockliner to the sole.   
   
   
       14 . Footwear as set forth in  claim 13  wherein the tabs each comprise a shaft and a head attached to the shaft. 
   
   
       15 . Footwear as set forth in  claim 14  wherein the openings in the sole have diameters less than diameters of the heads of the tabs. 
   
   
       16 . Footwear as set forth in  claim 15  wherein the heads of the tabs are resiliently deformable for allowing the heads to snap into the cavities through the openings. 
   
   
       17 . Footwear as set forth in  claim 13  wherein the tabs are formed as one-piece with the sockliner. 
   
   
       18 . Footwear as set forth in  claim 17  wherein the cavities and openings are formed as one-piece with the sole. 
   
   
       19 . Footwear as set forth in  claim 13  wherein the sole includes a forward portion and rearward portion, each of the forward and rearward portions of the sole including at least one cavity and corresponding opening, the sockliner including a forward portion and rearward portion, each of the forward and rearward portions of the sockliner including at least one tab. 
   
   
       20 . Footwear as set forth in  claim 13  wherein the sole is made of EVA and has a hardness, and the sockliner is made of EVA and has a hardness less than the hardness of the sole.
