Abstract: Footwear for improving the visibility of the wearer uses a circuit including a mechanically operated pressure switching mechanism, disposed in the footwear, to turn a lighting system off and on. The switch is responsive to pressure from the foot of the wearer. When a wearer raises a foot from the ground, the lighting system is activated. When the foot is returned to the ground, the lighting system is deactivated. The system may be disabled by removing a source of power from the circuit, or through the provision of a mechanically operable deactivation mechanism.

Abstract: An athletic shoe (20) having an inflatable air bladder (52) integrated into the design and construction of the shoe, and apparatus (50) for inflating the air bladder, as well as apparatus (82) for sensing and indicating the pressure in the bladder, all incorporated into the design of the shoe.

Abstract: An athletic shoe (20) includes a sole (22), an upper (25), and a tongue (26), as well as fasteners (28), such as shoelaces. Incorporated into the sole (22) of the athletic shoe (20) is a receptacle (30) for receiving and retaining a plug-in module (32) in a slide-in, releasably locking arrangement. The plug-in module (32) preferably includes a battery (62), a light emitting device (54), and electrical circuit elements (58, 60, 72) arranged to selectively connect the battery (62) to the light emitting device (54).

Abstract: Lightweight, inexpensive footwear sole components (14, 18), comprising a midsole portion (14) and an outsole portion (18), are formed by a method that eliminates the need for adhesively attaching the two portions to each other, and comprises the steps of 1) Forming the midsole portion (14) to have a lower surface (17) and at least one opening (26) extending into it through the lower surface (17); 2) Forming the outsole portion (18) on the lower surface (17) of the midsole portion (14) such that the outsole portion has an upper part (28) extending into the opening (26) in the midsole portion; and, 3) Forming a mechanical attachment device (22) between the outsole portion (18) and the midsole portion (14) on an upper end (19) of the outsole portion (18).

Abstract: An inertially responsive lighting system (10) for footwear has at least one electric light source (12), a battery (16), circuit means (22) to connect the battery to the light, and electro-mechanical switching means (24) disposed in the circuit means that are responsive to an inertial impulse force acting on the footwear to cause the light to flash on and off for a brief interval after the force is applied.

Abstract: Footwear for improving the visibility of the wearer includes a processing circuit that responds to operation of switch to turn a lighting system disposed in the footwear off and on. The switch is responsive to pressure from the foot of the wearer. When a wearer raises a foot from the ground, the lighting system is activated. When the foot is returned to the ground, or at the expiration of a predetermined period of time, the lighting system is deactivated.

Abstract: An improved module of the type having a light emitting diode and a wafer battery held in the case. The module has a case having a floor, a lighted end and an LED supporting cavity at the lighted end. An LED is supported in the case so that its lower conductor is adjacent the floor and its upper conductor is supported in a cantilevered manner from the transparent lens portion of the LED. A wafer battery having a positive and a negative terminal on each side thereof, is positioned so that one of its terminals continuously contacts the lower conductor of the LED and the upper conductor is positioned so that it is spaced from the other terminal of the wafer battery. A weight member is held above the upper terminal of the LED and the weight member has sufficient weight so that it will move the upper conductor downwardly when the weight is moving downwardly by inertia but will not have sufficient weight to move the upper conductor into contact with the wafer battery when the module is at rest.

Abstract: A speed closure (100) for footwear (10) comprises an elastic instep strap (110) having ends (111, 112) on opposite sides of the wearer's foot. The ends of the strap terminate in pulleys (114, 115) interleaved between the tongue (28) and respective ones of the flaps of the shoe for independent, sliding movement therebetween. A foldable fastening tab (120) is moveably attached to the tongue of the shoe. A tensioning line (140) having ends joined to form a continuous loop is threaded in an ordered sequence through eyelets (34) in the flaps, eyelets (127) in the tab, and the line pulleys, such that the line does not pass through any pulley more than once, and through any eyelet more than twice, and such that the line does not cross over itself. A cowl (150) is disposed over the instep of the shoe to cover portions of the instep opening of the shoe, the tongue, and the tab. The cowl has a top edge (151) and sides that lap past the flaps and attach to respective sides of the shoe.

Abstract: Footwear (1) adapted to enhance the visibilty of the wearer contains a light source (12), a power source (14), circuitry (15, 16, 17) to connect the power source (14) to the light source (12) , and a pressure switch (18) disposed in the sole (5) of the footwear (1) between the wearer's foot and the ground and adapted to turn the light source (12) off when the wearer's foot is on the ground, and hence static, thereby conserving the power source (14), and to switch the light source (12) on when the wearer's foot is off the ground, and usually moving, thereby providing enhanced visibility of the footwear (1) and its wearer.
