Impact-attenuating elements for footwear or the like may include (a) a first impact-attenuating material (e.g., foam) in a first region; and (b) a second impact-attenuating material in a second region (e.g., foam of a higher density). At least one characteristic of the impact-attenuating characteristics (e.g., support) provided by the impact-attenuating element may be controlled by changing a position or orientation of at least a portion of the impact-attenuating element in the footwear. For example, the “firmness” of the support provided by the impact-attenuating element may be changed by rotating or flipping the impact-attenuating element so that foam of a different density is provided at different areas of the foot. |
