Patent number: 6058627Abstract: An article of footwear includes a sole having a cavity formed therein and a plurality of holes extending from the cavity to the bottom surface of the sole. A spike is disposed in each one of the holes, and each spike is translatable between an extended position wherein a first end of the spike protrudes from the bottom surface of the sole and a retracted position wherein the first end does not protrude from the bottom surface of the sole. A slide member is slidably disposed in the cavity and has a plurality of recesses formed in a first surface thereof which is oriented towards the spikes. The slide member is translatable in a lengthwise direction between a first position wherein the recesses are aligned with the spikes so that the spikes assume their retracted position and a second position wherein the recesses are not aligned with the spikes so that the spikes assume their extended position.Type: GrantFiled: January 20, 1999Date of Patent: May 9, 2000Inventors: Richard R. Violette, Joyce V. Sawtelle

Patent number: 5956870Abstract: A shoe has spikes that can be retracted merely by moving an external operating member. Replaceable lower sole members can be selected and attached to the shoe based on ground surface conditions. Also, a shoe package includes one shoe with spikes and one shoe with retractable spikes or without spikes. A method of swinging a golf club using the shoe package permits a golfer's rear foot to be firmly planted while allowing the golfer's front foot to rotate and glide thus facilitating proper follow through.Type: GrantFiled: November 3, 1997Date of Patent: September 28, 1999Inventors: Gerald Grossman, Thomas Roney

Patent number: 5946828Abstract: A spiked athletic shoe includes a shoe upper, and an outsole housing connected to the shoe upper. The outsole housing includes a bottom wall with a plurality of spike-receiving openings. Spaced-apart rear and front spike plates are located within the outsole housing, and reside respectively in a rear heel portion of the shoe and a front portion of the shoe generally in an area of the ball and toes of the foot. The rear and front spike plates include a plurality of spikes attached thereto for movement between a spike-extended position whereby the plurality of spikes extend outwardly from the bottom wall of the outsole housing, and a spike-retracted position whereby the plurality of spikes are retracted within the outsole housing. A slide plate located within the outsole housing operatively engages the rear and front spike plates, and is actuated by a manually actuated lever to move the rear and front spike plates and attached spikes between the spike-retracted position and the spike-extended position.Type: GrantFiled: April 14, 1998Date of Patent: September 7, 1999Assignee: J.

Patent number: RE40460Abstract: A removable cleat for a shoe is described. The cleat includes a ground-engaging structure for engaging the ground. An attachment structure is for removably attaching the cleat to the footwear. The attachment structure has a vertical axis, a base to which the top of the ground-engaging member is attached, and multiple extensions projecting radially outward from the base. The extensions are adapted for insertion into a cleat receptacle in the shoe to engage a receptacle attachment structure within the receptacle, so that when the cleat is attached to the receptacle, each cleat extension will be securely engaged above a receptacle restraining ledge.Type: GrantFiled: May 18, 2004Date of Patent: August 19, 2008Assignee: Cleats LLCInventor: Armand J.
