         2 . The footwear system of  claim 1 , 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, and wherein the toe section of the first footwear article forms a corresponding fit with the toe cap of the second footwear article without forming an interlocking engagement therebetween. 
     
     
         6 . The footwear system of  claim 1 , wherein the raised ridge portion and the raised heel portion form a continuous singular pocket beginning on a lateral edge of the second footwear article and extending toward the raised heel portion, wherein the continuous singular pocket is designed to accept 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 a lateral edge of the second footwear article, extending around the raised heel portion, and ending on a medial edge of the second footwear article, wherein the continuous singular pocket is designed to accept the wing of the first footwear article. 
     
     
         8 . The footwear system of  claim 7 , wherein the second footwear article further comprises a lateral pocket, the lateral pocket having internal dimensions corresponding to external dimensions of a lateral portion of the wing. 
     
     
         9 . The footwear system of  claim 1 , wherein following contact between the first footwear article and second footwear article, the wing of the first footwear article contracts while entering the cavity of the second footwear article, and then expands filling the cavity. 
     
     
         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 raised heel portion with a user's opposing foot and unlocking an attachment between the first and second footwear 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 system 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. 
     
     
         16 . The footwear system 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. 
     
     
         17 . 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 the toe section of the first footwear article into the toe cap of the second footwear article; and   exerting downward force to apply pressure to the wing of the first footwear article to insert the wing of the first footwear article into the cavity of the second footwear article, a lateral portion of the wing interlocking with a lateral pocket of the second footwear article, a heel portion of the wing interlocking with a heel pocket of the second footwear article, and a medial portion of the wing interlocking with a medial pocket of the second footwear article.   
     
     
         18 . 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 a heel of the first footwear article with a user's opposite foot; and   unlocking an attachment and releasing the second footwear article from the first footwear article, a lateral portion of the wing unlocking from a lateral pocket of the second footwear article, a heel portion of the wing unlocking from a heel pocket of the second footwear article, and a medial portion of the wing unlocking from a medial pocket of the second footwear article.   
     
     
         19 . The footwear system of  claim 1 , wherein the wing extends to the front end of the first footwear article. 
     
     
         20 . The footwear system of  claim 1 , wherein a bottom portion of the sole of the second footwear article increases in thickness spanning from a toe section of the second footwear article to a heel section of the second footwear article, wherein the raised ridge portion and the raised heel portion form a continuous singular pocket beginning on a lateral edge of the second footwear article, extending around the raised heel portion, and ending on a medial edge of the second footwear article, wherein the continuous singular pocket is designed to accept the wing of the first footwear article, and wherein the second footwear article further comprises a lateral pocket, the lateral pocket having internal dimensions corresponding to external dimensions of a lateral portion of the wing.
