Abstract: Grind shoe device of the present invention includes a shoe sole having downwardly facing heel and forefoot tread surfaces and a downwardly opening recess formed with longitudinal and transverse recess sections. A grind plate device is formed with transverse and longitudinal grind plate sections for receipt in the respective transverse and longitudinal recess sections, at least one of such grind plate sections being formed with a downwardly facing trough for grinding along a rail, curb or the like. The longitudinal grind plate section is flexible and in some embodiments is foiled of rigid sections of discrete rigid grind plate portions disposed to flex relative to one another to facilitate flexing of the sole. The method of the present invention involves the manufacturing of the sole with such downwardly facing recess and fabricating the grind plate device to be complementally received in its top side in such recesses.

Abstract: An article of athletic footwear with a sole having a downwardly opening recess removably mounting a low friction grind plate for sliding across a protruding feature on a supporting surface and including an accessible storage compartment for temporarily storing keys and the like.

Abstract: An article of athletic footwear with a sole incorporating low friction surfaces for sliding across a protruding feature on a supporting surface and walking surfaces for other athletic pursuits, and a method of making same.

Abstract: A grinding shoe apparatus for both normal running and walking activity and including a sole cavity for mounting a complementary plate configured with a plurality of bearing surfaces for sliding along rigid support surfaces and braking surfaces to control speed developed while sliding.

Abstract: A method of making a grinding shoe involving constructing a sole of high friction material having a downwardly facing high friction surface interrupted medially by an upwardly raised recess having opposite sides curved outwardly to form flares and making a plate to conform to such recess and securing such plate thereto to provide a downwardly facing low friction grind surface.

Abstract: Articles of footwear incorporating one or more sliding elements are described. Such articles include shoes, sandals, boots, and appliances for attachment to any or all of the foregoing. In addition to serving the traditional functions of footwear lacking such sliding elements, such footwear can be used for recreational "grinding," or sliding across hard surfaces having edges, corners, etc.
