Patent number: 6115945Abstract: A construction for a shoe, particularly an athletic shoe, which includes a sole that conforms to the natural shape of the foot shoe, including the bottom and the sides, when that foot sole deforms naturally by flattening under load while walking or running in order to provide a stable support base for the foot and ankle. Deformation sipes such as slits or channels are introduced in the shoe sole along its long axis, and other axes, to provide it with flexibility roughly equivalent to that of the foot. The result is a shoe sole that accurately parallels the frontal plane deformation of the foot sole, which creates a stable base that is wide and flat even when tilted sideways in extreme pronation or supination motion. In marked contrast, conventional shoe soles are rigid and become highly unstable when tilted sideways because they are supported only by a thin bottom edge.Type: GrantFiled: December 3, 1993Date of Patent: September 12, 2000Assignee: Anatomic Research, Inc.Inventor: Frampton E. Ellis, III

The plate is movable within the upper between a spike-exposing position whereby the plurality of spikes extend outwardly through respective openings formed in the outsole, and a spike-retracting position. An inflatable bladder is located between the plate and the outsole. When inflated with a fluid, the bladder lifts the plate upwardly into the spike-retracting position, and holds the plate in the spike-retracting position during shoe wear. An exhaust communicates with the bladder for exhausting the fluid contained in the bladder. When the fluid is exhausted, the plate is movable into the spike-exposing position by the weight of the wearer during shoe wear.Type: GrantFiled: March 1, 1995Date of Patent: June 18, 1996Inventor: J.

Patent number: 5505012Abstract: The present invention relates to a directionally yieldable cleat assembly attached to an athletic shoe having an upper and a sole with a longitudinal axis. A plurality of spaced cleats are mounted to the sole so that the cleats protrude outwardly from the bottom of the sole. In one embodiment, a bumper is provided between the cleat and the sole for enabling a greater magnitude of deformation or deflection of the cleat in response to a predetermined lateral force imposed upon the cleat in a first laterally inward direction with respect to the longitudinal axis of the shoe than the deformation or deflection of the cleat in response to the same predetermined force imposed on the cleat in direction other than the first lateral direction. Deflection of the cleat is also minimized or eliminated in response to forces imposed on the cleats in a parallel direction to the longitudinal axis of the sole to ensure that traction for the shoe is uncompromised.Type: GrantFiled: November 29, 1994Date of Patent: April 9, 1996Assignee: Andrew S. WalkerInventors: Andrew S. Walker, Elwyn Gooding

Patent number: 5485687Abstract: An anti-slip attachment device is provided for a shoe having a sole and a vamp, which consists of a plate to fit against the bottom of the sole of the shoe. A component is for mounting the plate in a removable manner against the bottom of the sole of the shoe, so that the plate when mounted will be in a stationary position with respect to the sole. A structure on the bottom of the plate is for preventing the sole of the shoe from slipping on an icy surface.Type: GrantFiled: March 28, 1994Date of Patent: January 23, 1996Inventor: Gilbert Rohde

Patent number: 5465507Abstract: An integral sole for a shoe includes a base plate, a stabilizing plate, and a heel member. The base plate is made of a cushioning material and includes a lower surface having a footprint embossing which engages a walking surface providing traction and comfort for the user. The stabilizing plate is horizontally located about and surrounding the footprint embossing and is made of a material which is harder than the material of the base plate. The stabilizing plate also engages the walking surface and includes a bridge portion extending outwardly from a toe and ball portion of the footprint embossing to provide lateral stability for the sole. The heel member is located peripherally about a heel portion of the stabilizing plate. The heel member is made of a material which is harder than the material of the stabilizing plate to provide a firm heel stability for the shoe. Preferably, the toe portion of the footprint embossing includes five separate toe-print areas.Type: GrantFiled: April 13, 1994Date of Patent: November 14, 1995Assignee: OSAGE Footwear, Inc.Inventors: James H. Schumacher, Donald L. Mills

Patent number: 5458174Abstract: A threadedly engageable tire stud includes an elongated steel housing having a hexagonal head section and a threaded section of enlarged pitch for securely engaging a tire thread wherein the head section has approximately the same diameter as a major diameter of the threaded section. A longitudinally extended aperture is provided in the hexagonal head section for receiving an elongated carbide pin. The carbide pin is brazed to the elongated steel housing and protrudes out of the head section of the housing for engaging the road surface to improve traction of the tire.Type: GrantFiled: June 14, 1994Date of Patent: October 17, 1995Assignee: Bruno Wessel, Inc.Inventor: Rolf E. Wessel

Patent number: 5423135Abstract: A sole construction for use with a boating shoe or the like comprises an outsole having a multiplicity of wave-like incisions in a traction area. The incisions are each in the form of a flattened sine wave and extend generally transverse to the longitudinal axis of the sole. A plurality of straight incisions intersect the wave-like incisions and extend substantially parallel to the longitudinal axis of the sole. The sole may further include inner and outer traction areas in which a plurality of incisions intersect wave-like incisions extending parallel to the longitudinal axis of the shoe, with the straight incisions extending substantially transverse to the longitudinal axis.Type: GrantFiled: July 9, 1991Date of Patent: June 13, 1995Assignee: The Timberland CompanyInventors: Charles Poole, Gary Duclos
