Interlocking shoe structure

Abstract

A system for attaching a shoe to a skateboard is described. An interlocking structure attached to the shoe substantially prevents vertical and/or lateral movement of the shoe in relation the skateboard when the interlocking structure is pressed against another interlocking structure. The interlocking structures may register in a plurality of vertical and/or lateral positions. One or both of the interlocking structures may comprise a plurality of protrusions of a pointed or rounded shape.

1 . An interlocking shoe, comprising:
 a shoe having a first interlock structure attached to an outer portion thereof, the first interlock structure comprising a plurality of protrusions configured to substantially prevent vertical movement or to substantially prevent lateral movement of the shoe in relation to a second interlock structure when the first interlock structure is transversely pressed against the second interlock structure, and   wherein the first interlock structure and the second interlock structure can register in a plurality of lateral positions or vertical positions.   
     
     
         2 . The shoe of  claim 1 , wherein the first interlock structure is substantially permanently attached to the outer portion with an adhesive or stitching. 
     
     
         3 . The shoe of  claim 1 , wherein the first interlock structure is releasably attached to the outer portion with hook and loop fasteners. 
     
     
         4 . The shoe of  claim 1 , wherein the first interlock structure is integral to at least part of the outer portion. 
     
     
         5 . The shoe of  claim 1 , wherein the plurality of protrusions comprise a plurality of substantially pyramidal shapes. 
     
     
         6 . The shoe of  claim 1 , wherein the plurality of protrusions comprise a plurality of substantially hemispherical shapes. 
     
     
         7 . The shoe of  claim 1 , wherein the plurality protrusions comprise a plurality of substantially triangular shapes. 
     
     
         8 . The shoe of  claim 1 , wherein the protrusions of the first interlock structure comprises a plurality of substantially semicircular or semispherical shapes. 
     
     
         9 . The shoe of  claim 1 , wherein the plurality of protrusions are arranged in a vertically or laterally repeating pattern. 
     
     
         10 . The shoe of  claim 1 , wherein the first and second interlock structures are substantially complementary. 
     
     
         11 . The shoe of  claim 1 , wherein the first interlock structure is distally attached to an outer portion of the shoe. 
     
     
         12 . The shoe of  claim 1 , wherein the first interlock structure is proximally attached to an outer portion of the shoe. 
     
     
         13 . An interlocking shoe, comprising:
 a shoe comprising a first interlock structure on an outer portion of the shoe; the first interlock structure configured to engage a second interlock structure so as to substantially prevent vertical movement, lateral movement, or both when the first interlock structure is transversely pressed and maintained against the second interlock structure by a transverse movement of the shoe by a user,   wherein the first interlock structure is configured to disengage the second interlock structure when transverse pressure by the user is discontinued.   
     
     
         14 . The shoe of  claim 13 , wherein the first interlock structure and the second interlock structure can register in a plurality of lateral or a plurality of vertical positions. 
     
     
         15 . The shoe of  claim 13 , wherein the first and second interlock structures are substantially complementary. 
     
     
         16 . The shoe of  claim 13 , wherein the first interlock structure is distally attached to an outer portion of the shoe. 
     
     
         17 . The shoe of  claim 13 , wherein the first interlock structure is proximally attached to an outer portion of the shoe. 
     
     
         18 . The shoe of  claim 13 , wherein the first interlock structure comprises a plurality of protrusions. 
     
     
         19 . The shoe of  claim 18 , wherein the plurality protrusions comprise a plurality of substantially triangular shapes.
