Components for articles of footwear and athletic equipment are provided including a foam. A variety of foams and foam components and compositions for forming the foams are provided. In some aspects, the foams and components including the foams can have exceptionally high energy return while also having improved durability and softness. In particular, midsoles including the foams are provided for use in an article of footwear. Methods of making the compositions and foams are provided, as well as methods of making an article of footwear including one of the foam components. In some aspects, the foams and foam components can be made by injection molding or injection molding followed by compression molding.

A shoe having an upper and a sole connected to the upper. The upper has, at least in part, a knitted material forming its outer surface. To ensure sufficient longitudinal elasticity in the forefoot region and a good fit, along with efficient production, the knitted material consists of a first knitted material layer produced from a first thread, wherein the first material layer has arranged on it a second knitted material layer produced from a second thread. The second material layer at least partially covers the first material layer. In the region of the front half, as seen in the longitudinal direction of the shoe, and/or in the heel region of the shoe, the second material layer runs, at least in part, in strip form in a direction transverse to the longitudinal direction of the shoe so as to form a number of strips running parallel to one another.

An upper comprising a flexible layer configured to receive a foot, a bladder coupled to an outer surface of the flexible layer, and an inflation mechanism operatively coupled to the bladder for inflating the bladder such that the flexible layer is drawn toward the foot. The bladder extends from a lateral side in a heel region across a throat region to a medial side in the heel region. The bladder comprises a plurality of fluidly connected segments, each segment forming an angle with an adjacent segment.

A shoe that includes a sole assembly, an upper including a vamp and a tightening device. The tightening device includes keepers, a single lace having a tightening portion in a lacing path, and a blocking element having an active state for fixing a length of the tightening portion of the lace. The tightening device includes a vamp keeper provided on the vamp of the upper, as well as a tension member configured to reversibly pass the tightening portion of the lace between the lacing path and a tightening path when the blocking element is in the active state.

Systems, methods, and software products analyze foot strikes. A runner profile defining characteristics of a user and a shoe type of the shoes is received. Shoe characteristics are retrieved based upon the shoe type. A model of shoe wear is configured based upon both the runner profile and the shoe characteristics. Sensor data indicative of movement of a runner's foot is received from a foot strike monitor configured with the shoes and processed through the model to determine a user's expected lifetime for the shoes. The user's expected lifetime is indicated to the user.

A plate for an article of footwear includes a substrate, a first strand portion attached to the substrate via first stitching, and a second strand portion disposed on the first layer. The first strand portion includes first segments that each extend between two different locations along the substrate to form a first layer on the substrate. The second strand portion includes second segments that each extend between two different locations along the substrate to form a second layer on the first layer.
