This opportunity to utilize this wasted energy is obviously very tempting. One of my rejected ideas involves always wearing a top hat, however I will let your own creative speculation surmise as to why.

This particular Forward Momentum Dissipation Machine utilizes the same vertical motion of raising oneself onto the toes, but in a modified foot appliance. The shoe will have a steel frame installed that connects to the sides of the sole of the shoe. It will appear to be a toe guard, but can move one hundred and eighty degrees until having the appearance of a heel guard.

Once the wearer stops abruptly, they rear up onto their toes, which is covered by the toe guard. The Forward Momentum Dissipation Machine then supports the weight of the person and they continued forward until they land completely stopped with the device resting at their heels.
