A hidden drainage system for shoes, configured on the outsole of a shoe, in which the two sides of the outsole are provided with a plurality of curved sections that are curved inward; the top of the outsole is provided with a plurality of transverse drainage troughs and several longitudinal drainage troughs; each of the transverse drainage troughs extends along the direction of the width of the outsole, and both ends are communicated with each of the curved sections, so that the two ends of each of the transverse drainage troughs will not be exposed on the side face of the outsole; the longitudinal drainage troughs extend along the length of the outsole and are communicated with each of the transverse drainage troughs; thus, water entering the shoe will flow into each of the transverse and longitudinal drainage troughs, and be discharged from each of the transverse drainage troughs.

A pool sock having an upper portion comprising a water-resistant material and a reinforced toe protection area material and a lower portion comprising a waterproof, non-slip sole. The water-resistant material may be a polyester Lycra material and the sole may be a synthetic polyvinyl chloride and cotton blend. The pool sock may further include an entry/exit portion that is an elastic ring that is coupled to the water-resistant material of the upper portion. The entry/exit portion may be a flexible ring that is enclosed within the water-resistant material of the upper portion. The pool sock may further include a pull-tab coupled to either the entry/exit portion or the water-resistant material of the upper portion near a heel area. The toe protection area material may be vinyl, neoprene rubber, or leather. A bottom surface of the sole may include treads or ribs.

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.

A closable drainage system for a sole of a shoe, the closable drainage system including a drain configured to communicate between sole top and bottom surfaces of the sole, the drain having opposing drain upper and lower faces; at least one drainage aperture element disposed within the drain, the drainage aperture element defining a drainage channel which communicates between the drain upper and lower faces; and a movable member overlaying the drain upper face, the movable member movable over the drain upper face to provide open and closed conditions of the drainage channel; whereby in the open condition, the movable member disposes to allow passage through the drainage channel and correspondingly, between the sole top and bottom surfaces; and whereby in the closed condition, the movable member disposes to preclude passage through the drainage channel and correspondingly, between the sole top and bottom surfaces.

The shoe for bicycle competition, with a first member having a convex portion projecting on the bottom with the mounting surface to which a cleat is mounted for position adjustment, covering the heel, the side, and the sole of the feet integrally, the cleat for fixing to a bicycle pedal detachable, and the second member covering the sole to close the opening located on the opposite side of the convex portion. The first member forms an undercut shape with its lateral width narrower upward for the heel of the foot only to move forward, and the third member and the first member share the overlapping portion at least on the side surface of the foot, and by tightening the third member, be integrated by deformation and friction to form a monocoque structure.

A safety slipper (10) includes a stretchable fabric material upper portion (12) and a porous anti-skid lower portion. The upper portion has a foot opening (16) and a profile heel pocket (17). The lower portion (13) is made from a scrim cloth type material having a knit of polyester threads (21) coated with a soft poly-vinyl chloride outer layer (22). The lower portion provides for a cris-crossing pattern or matrix of interconnected nodes (23) with spaces (24) therebetween.

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.
