Impact-attenuating elements and customizable products containing such elements

A foot-receiving device, comprising:

• a foot-covering member;
• a foot-supporting member engaged with the foot-covering member;
• and
• an impact-attenuating element engaged with at least one of the foot-covering member or the foot-supporting member, wherein the impact-attenuating element includes a first region including a foam material having a first density and a second region including a foam material having a second density that is greater than the first density, and wherein the impact-attenuating element is movably or removably mounted with respect to at least one of the foot-covering member or the foot-supporting member so as to enable changing of at least one impact-attenuating characteristic of the foot-receiving device by changing a position or orientation of at least a portion of the impact-attenuating element with respect to at least one of the foot-covering member or the foot-supporting member.

A foot-receiving device, comprising:

• a foot-covering member;
• a foot-supporting member engaged with the foot-covering member, wherein the foot-supporting member includes a foot-contacting surface;
• an impact-attenuating element engaged with at least one of the foot-covering member or the foot-supporting member, wherein the impact-attenuating element is shaped and arranged such that an axial direction of the impact-attenuating element extends in a direction so as to pass through the foot-contacting surface;
• and
• means for varying at least one impact-attenuating characteristic of the impact-attenuating element.
