ABSTRACT:
Impact attenuating/spring systems may include first and second body portions and at least one spring member at least partially included between the body portions. The spring member(s) may substantially enclose and/or be pivotally engaged with the body portion(s). The components of the impact attenuating and spring element may be arranged such that when a force is applied to the body portion(s), the spring member(s) will exert a counter force to urge the impact attenuating and spring element back toward its original orientation. The spring members may include one or more polymeric element that stretches under a tensile force. The impact attenuating and spring elements may be included in a piece of footwear or other device in a manner such that a user or a retailer (or others) can select an appropriate spring member (or portion thereof), e.g., depending on characteristics of the user or the intended use.
