  • Patent number: 6763616
    Abstract: 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 horizontal plane of the shoe sole 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.

  • Patent number: 6684531
    Abstract: This invention is a spring shoe whose sole is a structure constrained to compress without tilting. This optimally simple, anti-tilt, compressible structure comprises overlapping diamond and parallelogram linkages, which constrain an upper plate from tilting as it moves vertically up and down with respect to a lower plate. Applications include a space shoe with push-off means for natural foot action. Here, a minimal number of springs and stops can be changeably incorporated in the sole to optimi8ze walking and running performance. A heel hugger mechanism ensures that the shoe hugs the heel of the wearer during swing phase. A flex-rigger prevents sideways rollover and sprained ankles. The first shoe embodiment has springs at shoe level to minimize device weight at foot level. The shoe is energy-efficient as it returns maximum impact energy to the runner during thrust at toe-off.

Discrete sole elements are attached to a bottom side of the upper so as to expose certain portions of the bottom side therebetween. This absence of outsole material in those areas makes the upper collapsible about those areas since the outsole provides no support in those areas. Instead, the structure is provided by the chassis of the chassis, which is customized to the user's foot by placing one or more notches in strategic locations along the chassis where the foot naturally flexes. One such notch is located on the chassis in a position that allows the chassis to flex about a forward push-off axis of the foot that runs through the first and second MTP joints.

  • Patent number: 6581305
    Abstract: The present invention is directed to a footwear construction having an insert of unitary structure and made of a single flexible material for providing increased structural support and strength of the footwear while maintaining flexibility of the footwear. Unlike the prior art insert, the present invention makes use of only a single material is used to manufacture the insert. A preferred material should be pliant or flexible and yet can provide the strength and structural support to the footwear in which the insert is used. Instead of using materials of different softness for the various sections in the insert to facilitate bending of the footwear, openings are added to various locations in the insert to facilitate planar bending movement. Such openings are commonly located in the forefoot section. To increase structural support and strength to the footwear, the insert is fixedly secured to the footwear.

  • Patent number: 6519876
    Abstract: A footwear structure including an upper and a separate midsole having interlocking shank portions. The upper has an upward extending arc in the shank area which defines a shank interlock portion therein. The midsole has a corresponding arc which defines a shank interlock portion on a bottom surface thereof which mates with the arc in the upper for resisting motion of the midsole relative to the outsole in the case where the midsole is unsecured within the structure to allow for removal of the midsole. The structure may include an outsole having a shank interlock area that mates with the shank interlock of the midsole, with or without an upper disposed between the midsole and the outsole. The shank interlock areas may include a continuous arc or an abruptly changing arc, and the midsole may be removable or non-removable from the structure. A rigid shank insert may be provided between the midsole and outsole, and the midsole may include a variety of layers.

  • Publication number: 20030005600
    Abstract: A midsole structure for an athletic shoe includes a midsole (3) formed of a soft elastic material and extending from a shoe heel region through a midfoot region to a forefoot region and a plastic shank member (10) or shankpiece and provided at regions that cover a midfoot portion (B) of the midsole (3) and having an oblong cross sectional shape where a dimension (W) in a shoe elongated direction is greater than a dimension (h) in the vertical direction. Thus, flexural rigidity of the midfoot portion (B) of the midsole (3) increases. When a bending moment is applied to themidsole (3), the shankmember (10) effectively exercises a so-called “shank effect” and thus, bending deformation can be prevented from occurring at the midfoot portion (B) of the midsole (3). As a result, flexibility or bendability of the forefoot portion (C) of the midsole (3) can be relatively advanced.
