    Abstract: A step-in apparatus and counter for a shoe are provided. The step-in apparatus allows a wearer to easily put on and take off a shoe without bending over, manipulating shoe laces, or using a shoe horn. The step-in apparatus and related counter allow the counter to deform and then return to its original shape without damaging the structural integrity of the counter or the shoe. This controlled deformation allows for ease of foot entry and exit without the need for laces, gores, or external devices such as shoe horns. The present invention is useful for those that lack the physical dexterity to bend over, tie shoe laces, or otherwise put on and take off shoes. In addition, the comfort and ease of use of the present invention makes for a new shoe that has universal appeal.

  • Patent number: 5127170
    Abstract: A new athletic shoe is disclosed suitable for packing in small suitbags or luggage for travel. A moveable or a detachable heel portion of the upper of the shoe allows the remainder of the upper to be collapsed to form a thinner shoe. Further, flexible soles may be used with inserts for providing rigidity, thereby allowing the toe of the shoe to be flexed back to the heal of the shoe allowing for a shorter, more compact structure for storage.

  • Patent number: 4941273
    Abstract: A shoe has an artificial tendon system, including an elastic band extending through a passageway in the midsole of the shoe. One end of the elastic band is attached to the midsole within the passageway near the forefoot area and the other end is attached near the heel area of the shoe. When the shoe is used, extension of the elastic band stores energy during heelstrike and early propulsion and releases energy during toeoff.

  • Patent number: 4821430
    Abstract: Footwear having a heel counter comprised of a stiff resilient material, especially an athletic shoe for medium and long distance running, is improved so that a better pressure distribution is assured on the outersole, and also on a possibly existing middle sole, in the area of the heel counter. This is achieved by the fact that the surface area which is enclosed by the sidewalls of the heel counter is provided with a pressure distribution membrane which is connected to a thicker reinforced lower arcuate edge of the sidewalls of the counter, and the pressure distribution membrane is suitably contoured to facilitate the improved distribution of heel pressure to the midsole and outer sole. Downward arching of the distribution membrane under heel pressure applied by the foot of a wearer causes an upper edge area of the sidewalls to be drawn inwardly to hold the heel with greater force.

  • Patent number: 4814037
    Abstract: The invention presents to the art a novel, improved shoe stiffener which comprises co-extruded layers of plastics film. The shoe stiffener comprises co-extruded layers of plastics film, a first of the layers comprising an ionomeric material and providing a main body of the stiffener and a second layer comprising a plastics material which does not adhere to a fusion press under conditions normally encountered therein during bonding of a shoe stiffener to a shoe upper. Nylon 6 is the preferred second layer plastics material. The co-extrusion product replaces fabric backed shoe stiffeners in which flaws induced in the film by the fabric may provide notches from which cracks in the material can propagate.
