The sidewall portion has a stiffness which varies along the length of the stabilizing device to provide a predetermined support profile along the side of the sole. The elongated portion can also vary in stiffness along its length. The stabilizing device can be formed of a resilient material using an injection molding procedure or similar technique.Type: ApplicationFiled: June 26, 2009Publication date: March 25, 2010Applicant: New Balance Athletic Shoe, Inc.Inventors: Sean Murphy, Edith Harmon-Weiss

Publication number: 20100071232Abstract: A shoe sole construction includes a sole member formed from a synthetic plastic material having a first durometer value of hardness and including toe, ball, arch, and heel portions. Relatively rigid toe and heel plates are secured to bottom surface of the sole member on opposite sides of a relatively soft flex bar member that extends transversely across the ball portion of the sole member. A plurality of toe cushion members are mounted for independent movement within openings contained in the toe plate, and a stabilizing arch cushion member is mounted in the recess defined in the heel plate. These cushion members have an intermediate durometer value that, during use, permits compression of these cushion members in a footprint pattern.Type: ApplicationFiled: September 25, 2008Publication date: March 25, 2010Inventor: George L.

Publication number: 20100037485Abstract: A slipper comprises a base layer and a first attachment layer formed on the top surface of the base layer, the base layer including a toe support area, an arch support area and a heel support area, and having flexible property. As the user wears the slipper and stands on the floor, the first attachment layer is pressed to completely attach to his foot. As the user raises his foot, the slipper will still attach to the foot by using the first attachment layer and become deformable with the foot's arching posture.Type: ApplicationFiled: August 13, 2008Publication date: February 18, 2010Inventor: CHI-KUNG WU

Publication number: 20100024247Abstract: A protective appliance for the space between the toes of a wearer of flip-flop sandals or other such footwear. The appliance has a generally hollow, generally elongated cylindrical shape and is fabricated from a relatively light weight, soft and compressible material. It includes a longitudinal cut through one of its sides that allows the appliance to be opened and engaged about the thong segment of the flip-flop that normally extends between the large toe and adjacent toe of the wearer, and that resiliently closes after the appliance is so engaged. When applied, the appliance cushions the space between the toes and the thong segment and allows at least a limited degree of both longitudinal and radial movement of the appliance relative to the thong segment thus increasing comfort of the flip-flops and minimizing friction and chafing of the toes on the thong segment during walking and other activities in the flip-flops.Type: ApplicationFiled: August 4, 2008Publication date: February 4, 2010Inventors: Daniel T. Feeney, John C. Hughes, Victor M. Souza, Timothy G. Hickey

Publication number: 20100011620Abstract: An impact absorbing material for a footwear article includes a first sheet having a plurality of projections for dispersing the force of an impact and a second sheet, having a lower durometer than the first sheet, that is bonded to the first sheet for absorbing the force from the projections. The projections are arranged on the first sheet such that nonlinear gaps are formed between adjacent pairs of projections. The impact absorbing material may be positioned between an upper and an inner liner of the footwear article and may be selectively positioned on the footwear article to protect an area on the wearer that is vulnerable to impact, such as the wearer's feet, ankles, heels or calves.Type: ApplicationFiled: July 15, 2008Publication date: January 21, 2010Applicant: WOLVERINE WORLD WIDE, INC.Inventor: Kiyotaka Nakano

Publication number: 20100000125Abstract: An article of footwear is disclosed that includes an upper that defines an interior void, a sole structure secured to the upper, and a foot-supporting insert that is positionable within a lower area of the void and removable from the void. A system having a protrusion and an indentation may be utilized to, for example, secure the insert within the void. As an example, a protrusion may extend outward from a surface of the void, and the insert may define an indentation in a corresponding location and with a corresponding shape. When the insert is positioned within the void, the protrusion will extend into the indentation. The locations, shapes, numbers and overall configuration of the protrusion and indentation may vary significantly.Type: ApplicationFiled: September 17, 2009Publication date: January 7, 2010Applicant: Nike, Inc.Inventor: Mario Angelbert Lafortune
