  • Patent number: 10441021
    Abstract: A footwear device is provided having a deformable heel contact member. The heel contact member extends above a top portion of the footwear's sole and deforms into a cavity formed in the sole when the user's heel applies a force against the heel contact member. The heel contact member is resilient and returns to its original shape when the force against the heel contact member is eliminated. The heel contact member is particularly well suited to reduce heel slap of open heeled footwear.

  • Patent number: 10244821
    Abstract: A sole structure of an article of footwear has a support assembly structure including a flexure element and an upper support element. The flexure element may have a central portion located between first and second ground-contacting or lower regions, wherein the central portion may have a downwardly concavely-curved shell-like region. The flexure element also may have first and second flanges extending upward from the first and second lower regions, respectively. The upper support element is positioned above the central portion and between the first and second flanges of the flexure element. When a vertical compressive load is first applied to the upper support element, the upper support element moves vertically relative to the first and second flanges. An article of footwear having the sole structure attached to an upper is also provided.

    Abstract: A pair of sport shoe inserts may be shaped differently to provide support to different areas of the feet during movement while participating in a sporting event. The right, back corner of the right foot may be supported by a lateral flange having an inclined slope that declines inwardly and forwardly. The left, back corner of the left heel may be supported with a lateral flange having an inclined slope that declines inwardly and forwardly, but at a smaller degree than with the right heel. The right heel may have a medial area that is uncovered or unsupported, such as to allow the right ankle to roll during a swing or other movement. The left heel may have a medial area that is supported with an arch or other support that may provide for push off during a swing or other player movement.

    Abstract: The shoe includes a shoe upper and a sole connected to the shoe upper. The sole includes an upper sole element, and a lower sole element. The shoe also includes an elongated spring element attached at both ends to the shoe upper, or attached at one to the shoe upper and the other end to the upper side element. The elongated spring element exerts a force on the upper sole element to pull the upper sole element away from the lower sole element. The upper sole element has a surface on which the sole of a foot of a wearer of the shoe rests during use of the shoe. The upper sole element rests on the lower sole element during use of the shoe due to the weight of the wearer of the shoe. The elongated spring element pulls at least a part of the upper sole element away from the lower sole element to separate the part of the upper sole element from the lower sole element, during non-use of the shoe. The elongated spring element can be a rubber band.

    Abstract: The shoe, has a shoe upper part and a sole. The sole has a supporting part, which is designed for receiving the heel region of the wearer's foot and is connected to the shoe upper part, and a sole element, which is connected to the supporting part. In order to improve the damping behavior of the shoe, the supporting part and the sole element are spaced apart from each other, in the longitudinal direction of the shoe. The connection between the supporting part and the sole element is preformed at two spaced-apart points in such a way as to form, under the heel region of the wearer's foot, a gap. The gap extends at least in portions over the entire width of the sole. The sole element, in the rear end region of the shoe, is connected to the supporting part.

  • Patent number: 8061060
    Abstract: Impact-attenuating elements, e.g., for use in footwear or other foot-receiving device products, may include: (a) a base member, such as a fluid-tight and/or other fluid-filled or fluid-containing enclosure element; (b) a support element integrally and contiguously formed in a surface of the base member; and/or (c) a spring device engaged with the support element. The support element and its corresponding spring device (if any) may include a non-planar surface (e.g., substantially parabolic shaped, cylindrically shaped, etc.) that extends in a direction into the base member and toward its opposite surface. The support element and its corresponding spring device (if any) also may include reinforcing structure(s), such as raised ribs extending along a surface of the support element and/or spring device.

  • Patent number: 8056261
    Abstract: A sole construction having a heel carrier and an upwardly-arched heel pad. The heel pad is fitted into and supported by the heel carrier so that the heel pad provides a spring-like bending reaction to a load. The sole construction may further include a support element disposed above the heel pad and fitted into heel carrier. The support element may be upwardly-arching so that, like the heel pad, it provides spring-like bending reaction in response to a load. The support element and heel pad may be integrally formed, for example, by molding the heel pad directly onto the support element. The heel pad and/or support element may be fitted into slots in the lateral and medial sidewalls of the heel carrier to interconnect the heel pad, support element and heel carrier. The support element may have a forward extension to function as a shank.

  • Publication number: 20110185593
    Abstract: The invention relates to an improved sole for footwear with a convex or rounded shape, provided with a stabilizer, with a damping system and with an internal system for the rotation of air, which modifies the phase of contact of the foot with the ground in a roller, such that it transforms the process of reception of the ground (with the heel of the foot) and forward translation of the propelling forces (by means of the area of the metatarsus and toes) in a roller effect, obtaining the damping/stability/impulse effects, and the actuation of the airing system by means of a pad/wedge, the outsole thus configured allowing a rotation on the ground such that the inertia of the body and the vertical forces applied from the heel of the foot are more easily converted into horizontal propelling forces.

  • Patent number: 7950167
    Abstract: A sole construction having a cushion insert that is installable in the sole at different orientations to vary the support/cushioning characteristics of the sole. The sole construction may include a midsole defining a receptacle configured to receive the cushion insert in a plurality of different orientations. The cushion insert and the receptacle may include a plurality of lobes that are interfitted when the cushion insert is installed in the receptacle. The size, shape and configuration of the lobes may be varied between different regions of the cushion insert so that different regions of the cushion insert provide different support/cushioning characteristics. The cushion insert and the receptacle may be generally disc-shaped so that the sole is adjusted simply by rotating the cushion insert with respect to the receptacle. The lobes may be configured so that rotation of the cushion insert adjusts the sole between supination, pronation, soft and firm settings.

    Abstract: A sole construction includes a cushion insert that is installable in the sole at different orientations to vary the support/cushioning characteristics of the sole. The sole construction may include a midsole defining a receptacle configured to receive the cushion insert in different orientations. The sole may be inserted into low-profile footwear having an outsole with a receptacle for retaining a corresponding differentiated heel portion of the sole. The sole may be included in a shoe construction having an outsole portion capable of bending or pivoting to provide access to the cushion insert for adjustment thereof. The sole may be included in a shoe construction having an outsole that defines an opening, through which the cushion insert may be accessed and manipulated. The cushion insert may include at least one channel that varies in depth about the insert so that different regions of the insert provide different support/cushioning characteristics.
