A force transfer system includes a body and an article. The article includes a first portion forming a first lateral axis and a second portion forming a second lateral axis, the axes being offset. An intermediate member is disposed between the first portion and the second portion, and holds the second portion to the first portion. A stimulus received by the first portion causes a temporary alteration of the intermediate member from an initial condition, the alteration of the intermediate member thereby causing a change in a characteristic of the second portion. The intermediate member subsequently returns to the initial condition, thereby causing a change in a characteristic of the first portion, which is influenced by the change in the characteristic of the second portion. The change in the characteristic of the first and second portions prevents at least a portion of the stimulus from reaching the body.
