Z-Coil
In the early 1980's, Alvaro Z. Gallegos was
running an average of seven miles a day. He suffered all the typical
injuries associated with running—heel spurs, plantar fasciitis, knee
trouble, hip pain, and back pain. And although he owned a shoe store at
the time and had access to all types of running shoes, he was unable to
find a shoe that eased his pain.
Realizing that the source of his pain was impact,
Al reasoned that putting a “shock-absorber” in the heel of his shoe
would reduce the force of impact. And as an added benefit, a spring
would provide some form of energy return, to help him run faster and
farther.
