An article of footwear including a sole structure attached to an upper defining an internal void configured to receive a foot of a wearer is described. The sole structure includes a sole body portion having a plurality of sensory node elements located in apertures in the sole body portion. The sensory node elements have a bottom surface configured to contact the ground and move vertically within the apertures. The movement of sensory node element pushes a top surface of the sensory node element attached to a portion of the upper against the foot of the wearer. The sensory node element provides sensory feedback to the foot of the wearer about the condition of the ground. The sensory node elements are arranged at discrete locations across the sole structure to provide sensory feedback at desired portions of the foot of the wearer.

A heel structure for an article of footwear protrudes rearward from a heel region of an article of footwear in a direction generally aligned with the longitudinal orientation of the footwear article.

In the sole, inequalities, m2m1, m1f and m1h are satisfied, wherein the rearmost end of the foot-sole-contact-side surface is set to the origin, the path measured along the surface from the origin to the tip of the toe is set to L, the sole thicknesses at the positions of Sh(0.16L), Sm2 {(0.3-0.5)L}, Sm1{(0.40.6)L} and Sf(0.7L) are set to h, m2, m1 and f, respectively. An inequality, 2>1 is satisfied, wherein the angle between the line connecting the positions Sm1, Sh and the horizontal plane is set to 1, and the angle between the line connecting the positions Sm1, Sh and the horizontal plane is set to 2, in which the position where the vertical lines drawn from the positions Sm1, Sh cross the ground-contact surface are set to Sm1, Sh, respectively. The ground-contact surface has a downwardly convexly curved shape at the forefoot region.

The present invention is directed toward an article of footwear effective to regulate the temperature of the feet of a wearer. In an embodiment, the article of footwear includes an upper and an insole with a thermal effect membrane. The thermal effect membrane contains a plurality of system-reactive components selectively engaged heat and/or moisture. In an embodiment, the printed coating includes a cooling agent, a phase change material, and a heat dissipation material. The bottom of the sole structure of the article of footwear further includes a multiple openings in the forefoot, midfoot, and hindfoot regions. The multiple openings promote airflow into the interior of the upper. In operation, the article of footwear is effective to delay/diminish the rise in skin temperature (compared to footwear lacking the membrane and/or openings), increasing wearer comfort.

The present invention relates to shoes which are an excellent fit and have improved comfortability and safety in use particularly in a wet place, and provides non-slip shoes with a webfoot in which a sole part and a webfoot part are integrally formed, thereby allowing walking and swimming at the same time.

A rocker shoe has a lower rocker surface extending across the plantar surface of the shoe sole from the heel and terminating short of the toe. A rocker shoe construction kit has a rigid or substantially rigid rocker piece having an upper surface for securing over a major portion of a lower plantar surface of the sole of a shoe upper and a lower surface of predetermined rocker shape, a cushioning layer for securing over the lower surface of the rocker piece, and a layer of tread material configured for securing over the lower surface of the cushioning layer and any exposed portion of the plantar surface of a shoe.

A sole includes an outer sole assembly including a plurality of outer sole members spaced apart from each other by a plurality of gaps. In addition, the sole includes a middle sole assembly defining a plurality of grooves, and an intermediate layer comprising an elastomer. The intermediate layer is disposed between the outer sole assembly and the middle sole assembly. The intermediate layer connects the middle sole assembly to the outer sole assembly. The intermediate layer is more elastic than each of the plurality of outer sole members. The intermediate layer is more elastic than the middle sole assembly. At least one of the gaps is vertically aligned with one of the grooves.

A heel structure for an article of footwear protrudes rearward from a heel region of an article of footwear in a direction generally aligned with the longitudinal orientation of the footwear article.

An improved sandal with several orthotic benefits is provided. The sandal has a unique combination of features what will be useful for the treatment and prevention of plantar fasciitis. The improved sandal has a medial split in the medial heel section of the sole. The medial split is designed so that it absorbs more energy than the other parts of the heel and promotes a lateral to medial rotation of the heel portion during the wearer's gait. In a preferred embodiment, the sandal will include a rocker bottom sole and raised bed for the big toe that begins its rise at the metatarsophalangeal joint. In an additional preferred embodiment, the sole of the sandal will also include a metatarsal bar that supports the traverse arch and an upward bend that begins to rise from the sole at a point just forward of the end of the medial split and intersects with the metatarsal bar.

A sole structure for an article of footwear comprises a midsole including a first cushioning layer, a second cushioning layer, and a third cushioning layer. The first cushioning layer has a central portion, and a peripheral portion surrounding the central portion. The first cushioning layer, the second cushioning layer, and the third cushioning layer are stacked with the second cushioning layer directly overlying the peripheral portion of the first cushioning layer, and the third cushioning layer overlying the second cushioning layer and directly overlying the central portion of the first cushioning layer. The first cushioning layer has a domed lower surface extending away from the second cushioning layer and the third cushioning layer and substantially centered under the central portion.
