A plate may also extend under a portion of the chamber.

Abstract: An article of footwear is disclosed that includes an upper and a midsole. A first midsole impact force attenuation structure or system is arranged at least within the toe region of the midsole. A second midsole impact force attenuation structure or system is arranged at least within the heel region of the midsole, such that the second midsole impact force attenuation structure or system includes a molded heel region member extending from a lateral side of the article of footwear to a medial side; the heel region member having a hollow central region defined by a first radius of curvature in a direction toward the toe region and a second radius of curvature in a direction toward the heel region. The first radius of curvature is different from the second radius of curvature. The heel region member may be in an asymmetrical stiffness construction.

Abstract: An article of footwear includes an upper and a sole assembly secured to the upper. The sole assembly has a shell having a first hardness and a recess. A lateral side of the recess has a first depth and a medial side of the recess has a second depth that is different than the first depth. A first aperture extends through a forefoot portion of the shell, with the first aperture defining a first tongue fixed on a medial side thereof with a remainder of the first tongue free to flex with respect to the shell. An insert has a second hardness and is seated in the recess. A lateral side of the insert has a first height and a medial side of the insert has a second height that is different than the first height, with the second hardness being different than the first hardness.

Abstract: Articles of footwear have a sole structure that extends along the longitudinal length of the article of footwear within the forefoot region, the midfoot region, and the heel region of the article of footwear. One or more removable inserts may be inserted into at least a portion of the sole structure in any desired region. Various removable inserts may have different characteristics, including different performance characteristics. The various removable inserts may be inserted into and removed from the sole structure of the article of footwear. A wearer may be able to compare the characteristics for each of the removable inserts.

Abstract: Impact-attenuating elements include a plurality of impact-attenuating members and a means for releasably securing the impact-attenuating element to at least one of the upper member or the sole member of a piece of footwear or other foot-receiving device. The impact-attenuating elements may be included in the footwear or other foot-receiving devices in a selectively removable manner so that a user, retailer, or another can customize and freely select an appropriate element, e.g., depending on user preferences, characteristics of the user, characteristics of the intended use, and the like.

Abstract: A system for custom fitting athletic shoes to an individual wearer includes a foot measurement device, an adjustable footform and an infrared activation chamber. Shoes of a single width for each length size have at least a portion of the upper made of heat malleable material to be custom fitted for width. Foot measurement data is used to calculate length size, width size and a number of custom adjustment factors. After the length size is calculated, the appropriately sized shoe and last are assembled together and subject to infrared radiation until the heat malleable material becomes plastic. Adjustments are then made to the last in accordance with the adjustment factors to provide custom width sizing. After further heat treatment to set the shoe upper and cooling, the shoe is complete. In this manner, if used in a retail setting, shoes are custom fitted to the wearer in a matter of minutes.
