A shoe having a structure with excellent acceleration performance is provided. A shoe includes: a sole made of a soft material, which includes a ground contact surface and also includes a foot contact surface facing a side opposite to the ground contact surface; and an upper combined with the foot contact surface side of the sole. A thickness of the sole at a position corresponding to an MP joint of a wearer is different from a thickness of the sole at a position corresponding to the center of the heel such that an angle between the foot contact surface and the ground contact surface falls within the range of 8 to 16 degrees. Accordingly, a shoe having a structure that provides excellent feeling of acceleration is provided.

An apparatus includes a heel section, a mid-foot section, and a toe section. The heel section, the mid-foot section, and the toe section collectively have a geometric shape having a first slope of a polarity along an inner edge of the apparatus from the toe section to the heel section and a second slope of the polarity along the inner edge of the apparatus to an outer edge of the apparatus at the toe section.

A pair of shoes that includes a left foot shoe and a right foot shoe. Each of the shoes include an upper shoe portion and a sole coupled to the upper shoe portion. The sole provides an athletic positioning of a left big toe area of the left shoe at a lower position than a left heel area of the left shoe and at a lower position than an outer small toe area of the left shoe and wherein, from an inner edge to an outer edge of the left shoe, the left heel area has substantially no slope.

A midsole for sports shoes having a front isolation cavity, a side cavity, and a rear isolation cavity partially separating the recessed arch portion of the midsole from the rest of the midsole.

A midsole for a shoe, in particular a running shoe, is described which midsole is asymmetric in a midfoot area, has an upper heel portion embracing the calcaneus of a wearer and has an upwardly extending toe end. In the midfoot area a vertical medial support structure originates from the midsole and supportively embraces the arch. Correspondingly, a vertical lateral support structure supports the lateral side of the foot in the midfoot area. The medial support structure covers a larger area than the lateral support structure, and is connected to the vertically extending upper heel portion of the midsole. The toe end of the midsole is extended upwardly, and provides in combination with the vertically extending upper heel portion and said vertically extending medial and lateral arch support structures a midsole which firmly embraces the foot. The result is a shoe, in particular a running shoe, which reduces the risk of injury during running.

A sole structure for an article of footwear is provided. The sole structure includes an outsole having a ground-engaging surface and an upper surface formed on an opposite side of the outsole than the ground-engaging surface. A first cushion is disposed proximate to a medial side of the sole structure and includes a first fluid-filled chamber attached to the upper surface of the outsole and a second fluid-filled chamber attached to the first fluid-filled chamber and disposed between the first fluid-filled chamber and the upper. A second cushion is disposed proximate to a lateral side of the sole structure and includes a third fluid-filled chamber attached to the upper surface of the outsole and a fourth fluid-filled chamber attached to the third fluid-filled chamber and disposed between the third fluid-filled chamber and the upper. The second cushion is fluidly isolated from the first cushion.

An article of footwear is provided having an elevated plate structure incorporated in the sole structure and optionally including a fluid-filled chamber. The elevated plate structure can include an upper plate and a plurality of legs extending downward toward the outsole. End portions of the legs can engage an upper region of the outsole. The elevated plate structure can form a cage region that can optionally include a fluid-filled chamber substantially disposed therein. The elevated plate structure can further include a lower plate disposed at an upper region of the outsole, which can form a lower portion of the cage region. Portions of the legs can be integrated with impact-attenuating members in the heel region in various configurations and can provide features for the impact-attenuating members, such as support, impact-attenuation and adjustable impact-attenuation features.
