Exterior shoe attachement and method of use thereof

Abstract

A footwear system including a first footwear article configured to accept a user's foot, the first footwear article having a body and a sole attached to the body, the sole having a flange member extending past the body forming a wing, and a second footwear article, the second footwear article comprising a sole having a raised ridge portion and a raised heel portion, the raised ridge portion and the raised heal portion forming a cavity configured to accept the wing of the first footwear article, wherein the second footwear article is configured to be detachably attached to the first footwear article.

1 . A footwear system, comprising:
 a first footwear article configured to accept a user's foot, the first footwear article having a body and a sole attached to the body, the sole having a flange member extending past the body forming a wing; and   a second footwear article, the second footwear article comprising a sole having a raised ridge portion and a raised heel portion, the raised ridge portion and the raised heal portion forming a cavity configured to accept the wing of the first footwear article,   wherein the second footwear article is configured to be detachably attached to the first footwear article.   
     
     
         2 . The footwear system of  claim 2 , wherein the first footwear article and the second footwear article form an interlocking engagement for use by a user. 
     
     
         3 . The footwear system of  claim 1 , wherein the wing compresses and interacts with the raised ridge portion and the raised heel portion to form the interlocking engagement between the first footwear article and the second footwear article. 
     
     
         4 . The footwear system of  claim 1 , wherein the wing is comprised of material that compresses when force is applied to the wing, and expands when the force is removed. 
     
     
         5 . The footwear system of  claim 1 , wherein the raised ridge portion of the second footwear article is comprised of a material that expands to accept the wing, and contracts to support an interlocking engagement between the first footwear article and the second footwear article. 
     
     
         6 . The footwear system of  claim 1 , wherein the raised ridge portion and the raised heel portion form a continuous singular pocket beginning on sides of the second footwear article and extending toward the raised heel portion, wherein the continuous singular pocket is designed to accept the emergence of a proportional counterpart comprising the wing of the first footwear article. 
     
     
         7 . The footwear system of  claim 1 , wherein the raised ridge portion and the raised heel portion form a continuous singular pocket beginning on sides of the second footwear article and extending toward the raised heel portion, and further extending toward a medial wall, wherein the continuous singular pocket is designed to accept the emergence of a proportional counterpart comprising the wing of the first footwear article 
     
     
         8 . The footwear system of  claim 1 , wherein following contact between the first footwear article and second footwear article, the first footwear wing slightly contracts while entering the cavity of the second footwear article, and then expands filling a pocket along the raised ridge and the cavity. 
     
     
         9 . The footwear system of  claim 1 , wherein the first footwear article and the second footwear article are resistant against accidental disengagement. 
     
     
         10 . The footwear system of  claim 1 , wherein the attachment and detachment of the first footwear article to or from the second footwear article is pressure activated. 
     
     
         11 . The footwear system of  claim 1 , wherein detaching the second footwear article from the first footwear article is accomplished by applying pressure to the heel with a user's opposing foot and unlocking the attachment between the articles. 
     
     
         12 . The footwear system of  claim 1 , wherein the wing extends around the sole's lateral edge and heel. 
     
     
         13 . The footwear of  claim 1 , wherein the first footwear article is selected from a group consisting of a shoe, slipper, sandal, boot, trainer, cleat, golf shoe, soccer shoe, or a combination thereof. 
     
     
         14 . The footwear of  claim 1 , wherein the second footwear article expands and contracts to accept the wing of the first footwear article to assist with attaching the second footwear article to the first footwear article. 
     
     
         15 . The footwear of  claim 1 , wherein the second footwear article further comprises a toe cap. 
     
     
         16 . The footwear of  claim 15 , wherein the toe cap provides additional toe injury protection for the wearer. 
     
     
         17 . The footwear of  claim 1 , wherein the second footwear article further comprises a strap substantially along a throat line to provide an additional support in securing the second footwear article to the first footwear article. 
     
     
         18 . The footwear of  claim 1 , wherein the second footwear article acts as a shock absorber and provides superior traction compared to the sole of the first footwear article. 
     
     
         19 . A method for attaching a first footwear article to a second footwear article, the method comprising:
 providing the first footwear article and the second footwear article of  claim 1 ;   inserting a toe portion of the first footwear article into a toe cap of the second footwear article; and   exerting downward force using at most a user's bodyweight to apply pressure near the heel of the first footwear article to insert the heel into the cavity of the second footwear article.   
     
     
         20 . A method for removing a first footwear article from a second footwear article, the method comprising:
 providing the first footwear article and the second footwear article of  claim 1 ;   applying pressure near the heel of the first footwear article with a user's opposite foot; and   unlocking the attachment and releasing the second footwear article from the first footwear article.
