The present disclosure provides shoe soles shoe soles configured to provide data about a subject's running mechanics, shoes incorporating same, and methods of making and using same.

An article of footwear has a midsole assembly that includes a fluid-filled bladder element having a substantially arc-shaped heel portion and having a lateral arm portion and a medial arm portion spaced from the lateral arm portion. Each of the arm portions extend from the heel portion. The bladder element is configured to be positioned with the heel portion in the heel region of midsole assembly, and the arm portions extending from the heel region to a forefoot region along a peripheral region. A method of manufacturing and a mold assembly for such an article of footwear are provided.

A sole structure for an article of footwear includes a midsole having a top surface and a bottom surface opposite the top surface, the bottom surface including a first recess. A first bladder is disposed within the first recess and a first outsole member is coupled to the midsole and includes a ground-engaging surface having a first traction element and a second traction element. The first traction element is aligned with the first bladder and defines a first height relative to the ground-engaging surface, the second traction element is aligned with the first bladder and defines a second height relative to the ground-engaging surface, the second height being greater than the first height.

A shoe sole includes a shock absorber that buckles when the shock absorber receives compressive force applied in a normal direction to a ground contact surface. When a load is applied to the shoe sole, the shock absorber starts to buckle in a state in which a stress occurring in the shock absorber is within a range from 0.15 MPa to 0.80 MPa and a strain of the shock absorber is within a range from 10% to 60%. When a time point at which a strain energy density of the shock absorber reaches 0.157 J/cm.sup.3 is defined as a specific time point, a maximum value of the stress occurring in the shock absorber until the specific time point is 0.80 MPa or less, and a tangential elastic modulus of the shock absorber at the specific time point is 5.00 MPa or less.

A method for forming a plate includes attaching a first strand portion to a flexible substrate to form a first layer on the substrate and positioning a second strand portion on the first layer to form a second layer on the first layer in a plurality of discrete regions on the substrate. The method also includes positioning a plurality of traction elements into corresponding cavities formed into a first mold surface and positioning the substrate on the first mold surface to change a shape of the substrate. At least one of heat and pressure is applied to the first strand portion, the second strand portion, the substrate, and the traction elements to conform the substrate to the shape of the first mold surface and form the traction elements into the substrate at each of the discrete regions. The method also includes incorporating the substrate into an article of footwear.

An article of footwear comprising a sole including a midsole and an outsole attached to the midsole, and a support member positioned on a bottom surface of the midsole, where the support member has a curved surface that extends from a rear end to a front end of the support member.

A sole structure for an article of footwear having an upper includes an outsole, a plate disposed between the outsole and the upper, and a first cushioning layer. The plate includes an anterior-most point disposed in a forefoot region of the sole structure, a posterior-most point disposed closer to a heel region of the sole structure than the anterior-most point, and a concave portion extending between the anterior-most point and the posterior-most point. The concave portion includes a constant radius of curvature from the anterior-most point to a metarsophalangeal (MTP) point of the sole structure. The MTP point opposes the MTP joint of a foot during use. The first cushioning layer is disposed between the concave portion and the upper.

An article of footwear includes an upper and a sole structure secured to an underside of the upper. The sole structure includes a midsole; a ground contacting outsole surface; and a cushioning system disposed between the midsole and the ground contacting outsole surface. The cushioning system includes a plate comprising an upper plate and a lower plate provided in a spaced relationship. The upper plate and lower plate are integrally connected at a posterior portion of the sole structure. The sole structure further including at least one of a midfoot fluid-filled chamber provided between the upper plate and the lower plate within the midfoot region, or a forefoot fluid-filled chamber is provided between the upper plate and the lower plate within the forefoot region.

A method for forming a plate includes attaching a first strand portion to a flexible substrate to form a first layer on the substrate and positioning a second strand portion on the first layer to form a second layer on the first layer in a plurality of discrete regions on the substrate. The method also includes positioning a plurality of traction elements into corresponding cavities formed into a first mold surface and positioning the substrate on the first mold surface to change a shape of the substrate. At least one of heat and pressure is applied to the first strand portion, the second strand portion, the substrate, and the traction elements to conform the substrate to the shape of the first mold surface and form the traction elements into the substrate at each of the discrete regions. The method also includes incorporating the substrate into an article of footwear.

Presented are footwear sole structures with foot-cushioning insoles movably mounted onto impact-attenuating midsoles, methods for making/using such sole structures, and footwear fabricated with such sole structures. A multilayered sole structure assembly includes an insole movably mounted on a midsole. The midsole is formed with a first compressible material and includes opposing upper and lower midsole surfaces, multiple protrusions projecting from the upper midsole surface, and multiple pockets recessed into the upper midsole surface and interleaved with the midsole protrusions. The insole, which is formed with a second compressible material distinct from the first compressible material, includes opposing upper and lower insole surfaces, multiple protrusions projecting from the lower insole surface and interleaved with the midsole protrusions, and multiple pockets recessed into the lower insole surface and interleaved with the insole protrusions. Each midsole protrusion nests within a respective insole pocket, while each insole protrusion nests within a respective midsole pocket.
