Patent number: 5884420Abstract: The present invention relates to a boot especially adapted to sports that require movement of the foot, or to gliding sports, including an upper provided with a rear stiffener surrounding the heel and an external sole. According to the invention, the stiffener is rigid and substantially non-flexible, and extends along at least one side of the boot, up to the so-called metatarsophalangeal bending zone. According to a second aspect of the invention, the stiffener is rigid and substantially non-flexible, and surrounds the heel and essentially the rear portion of the base of the foot, in the manner of a shell. This construction also allows for a better transmission of the forces, while maintaining a flexibility of the boot in the metatarsophalangeal zone, due to the reinforcement of the rear portion of the boot. These constructions permit a better control of the ski through the heel retention and, at the same time, a general gain of energy by eliminating the parasitic deformations of the sole and of the boot.Type: GrantFiled: January 21, 1997Date of Patent: March 23, 1999Assignee: Salomon S.A.Inventor: Thierry Donnadieu

Patent number: 5265350Abstract: A footwear device (2000) comprises a rigid base (2100) for supporting the foot (2001) of a user thereon, a medial forefoot counter (2201) associated with the rigid base (2100) for contact with the foot (2001) of a user medial to the medial aspect of the head of the first metatarsal, a heel counter (2300) on the rigid base (2100) for contact with the foot (2001) posterior to the posterior aspect of the heel and a forefoot/midfoot compression member (2400) for exerting a downwardly and rearwardly directed force on the dorsum of the foot (2001). The medial forefoot counter (2201), the heel counter (2300) and the forefoot/midfoot compression member (2400) cooperate with each other to be in substantially continuous contact with the user's foot (2001) in the above-mentioned areas, while the remainder of the foot is substantially unconstrained to accommodate the changing architecture of the foot (2001) when moving between bipedal and monopedal stances.Type: GrantFiled: February 3, 1992Date of Patent: November 30, 1993Assignee: MacPod Enterprises Ltd.Inventor: David M.

Patent number: 5218773Abstract: An athletic shoe with a torsional stabilizer incorporated therein comprises a substantially flat horizontal base member extending rearward across the width of the shoe, parallel to the sole of the shoe, from a transverse line located adjacent to and behind the phalangeal/metatarsal joints, at least to a line adjacent to, and forward of the heel portion of the shoe. Except for transverse edges forward of the heel-end, the base member is provided with a substantially vertical flange portion attached to the edges thereof, which serves to stabilize the base member relative to torsional forces acting thereon.Type: GrantFiled: October 21, 1991Date of Patent: June 15, 1993Inventor: Stanley Beekman

Patent number: 5172494Abstract: A foot cushioning device to absorb shock primarily shock due to heel strike which device is insertable in or may be incorporated in footwear. The exterior of the body of the device carries primary shock absorbers extending at least from the portion of the device in the heel area. The primary shock absorber deforms to protect the foot by absorbing initial shock loads. Secondary shock absorbers are also provided which with increased deformation will provide resistance to higher shock load so that a non-linear force displacement behavior similar to that occurring in the natural heel pad occurs. In the preferred embodiment, the body of the device is a heel cup and the primary and secondary shock absorbing members are defined by longer and shorter ribs extending longitudinally and transversely along the outer surface of the heel cup in a grid-like pattern.Type: GrantFiled: May 31, 1991Date of Patent: December 22, 1992Inventor: Murray R. Davidson
