Z-COiL shoes are an very efficient and effective way to deal with foot, leg, knee, hip, and back pain. The built-in orthotic deals with heel spurs, plantar faciitis and aligns foot properly, correcting over pronation and supination. The spring in the heel works as a very effective shock absorber for the body, reducing shock and impact by as much as 50%!!
