Abstract: Impact-attenuation systems, e.g., for use in footwear, can help control foot positioning during a step cycle, e.g., to help reduce or eliminate misorientation of the foot, and the fatigue and/or strain that may result from such misorientation. Articles of footwear including such impact-attenuation systems may include: (a) an upper member; and (b) a sole structure engaged with the upper member. The sole structure may include: (i) a first impact-attenuating member located in a heel portion of the foot-supporting member, and (ii) a second, separate impact-attenuating member located at a rear, lateral heel portion. The second impact-attenuating member may be designed and/or configured to provide less resistance to an impact force as compared with the first impact-attenuating member.

Abstract: Impact-attenuation members include: (a) an impact-attenuating member and (b) a shear resistant member engaged with the impact-attenuating member. Another example impact-attenuation member includes a shear resistant member having a continuous wall that bulges outward on opposing sides when in an uncompressed base orientation. The shear resistant members may be structured and arranged to allow bending or compression against impact forces in one direction (e.g., when landing a step or a jump), but remain highly stable against shear or lateral forces in another direction (e.g., in a side-to-side direction). Such impact-attenuation members may be used in footwear products, including in athletic footwear.

The second impact-attenuating member may be arranged at a different orientation with respect to the longitudinal direction as compared to the first orientation. Impact-attenuation systems having the characteristics described above, as well as methods of making and using products containing such systems, also are described.

Abstract: Impact-attenuation members include body portions, optionally with an arched structure, that define a base orientation and an open space; and a spring member extending across the open space and engaging the body portion(s). When a force is applied to the body portion(s) in at least some orientations and/or directions of incident force, e.g., so as to change the impact-attenuation member out of its base orientation, the spring member may exert a force that urges the impact-attenuation member back toward the base orientation. Various example structures for the impact-attenuation member are described. Such impact-attenuation members may be used in articles of footwear or other foot-receiving device products.

Abstract: Impact-attenuation members, e.g., for use in footwear or other foot-receiving devices, include: (a) a first body member having a base region and three (or more) leg portions extending from the base region. A second body member, with similar leg portions, may be arranged facing the first member such that the free ends of the various leg portions lie adjacent one another. A retaining member may extend between and/or at least partially around the body members to at least partially hold them in place with respect to one another. Such impact-attenuation systems may be arranged in the heel (or other portions) of an article of footwear.
