The present invention involves footwear that utilizes tread members having generally rectangular arrays of lugs and protuberances on the lugs. Grooves separate the lugs and provide flow paths from the interior area of a tread member to the exterior. Sipes are positioned between the protuberances and form flow paths from the interior area of the lugs to the grooves. The tread members are positioned at least at the forefoot portion and heel portion of the outsole.

Embodiments of the present invention relate to a shoe construction that includes an upper that has an interior surface and a corrugated exterior surface of rapid manufactured material. The upper interior surface and corrugated exterior surface form a lattice-interlace surface. The lattice-interlace surface includes the interior surface that has a plurality of horizontal laths, the corrugated exterior that has a plurality of vertical laths, and a plurality of lattice apertures that extend from an interior of the shoe to an exterior of the shoe. The shoe construction further includes an interior sole portion of sintered material. The interior sole portion forms a tessellated framework. The tessellated framework includes a lattice of hollow cubes; each hollow cube has a top surface opening and a bottom surface opening, the openings extending from an interior of the shoe to an exterior of the shoe.

The present invention discloses a safer sole against slippage while worn wet, and one which is pleasant to wear, practical to use, and economical to manufacture. The invention discloses a footwear sole through an innovative means of allowing water to clear from a foot, and under a footwear. It is also the purpose of this invention to provide for an aerating sole via open through and through channels for improving foot hygiene while maintaining the safety of a foot from being poked or pricked if stepping on pointy objects.

A swimming/scuba diving fin having a blade, a shoe open at the rear, an adjustable elastic strap engageable around the heel of the scuba diver, and two buckles at opposite ends of said adjustable elastic strap connected to two opposed side walls of said shoe, where at least one said buckle has a shaped hollow body forming integrally a portion connecting to said side wall, a channel for the axial sliding of the adjustable elastic strap, and a releasable fastening clamp of the adjustable elastic strap, where such an axial sliding channel has a hole for the inlet of the adjustable elastic strap, a hole for the outlet of the adjustable elastic strap and a deflection angle of the adjustable elastic strap positioned between such an inlet hole and such an outlet hole.

A water or swim shoe for persons needing to wear an orthotic to support a foot for swimming or any other water exercise or recreation. The shoe body is comprised of porous, water resistant material, has multiple holes for water drainage, and a protective rounded rubber toe end. The shoe sole is comprised of rubber or synthetic rubber. The shoe sole has affixed thereto and extending from the heel end an “L” shaped hard plastic orthotic which is strapped to the back of the person's leg for wear.

A footwear article for watersports comprising a sole, a vamp in connection with the sole and an upper fixed with the vamp and the sole. A lacing system disposed on the upper, the lacing system comprises a lace, a first set of anchor points and a second set of anchor points. Said lacing system is disposed on an outer side of the upper and configured such that the lace crosses over itself fewer than six times between anchor points in the closed configuration; and wherein at least one of the vamp and the upper comprises a textured surface, and an upper comprises a strap adapted to extend around at least the perimeter of the upper.
