Z-CoiL Footwear is engineered to relieve foot, leg and back pain. It's patented, shock absorbing design greatly reduces impact to the body and distributes pressure more evenly across the foot than conventional shoes do. And less impact means less pain.Testimonial"I work at Durham Regional Hospital in the Pharmacy. I am on my feet all day. I have several orthopedic problems which causes me great pain each and every day. Since I purchased my Z-CoiL shoes, I have worn them everyday and I am able to come to work now without relying on my pain medication to be able to work. Z-CoiL shoes are awesome!!! I recommend them to anyone."​Pam S Timberlake, North Carolina
