I have been a Z-CoiL customer for years; they have kept me walking during severe Plantar Fasciitis. They have kept me going on cement brick floors, and now getting out of a high step van. Even so, I just put on this new pair of Haylee shoes that I bought for work and I immediately relaxed and started breathing deeper. Then I felt muscle relaxation and nerve tingling sensation all over my spine, as my whole body relaxed and adjusted to the shoes. This was a new experience even for me a long time Z-CoiL customer. Thanks Z-CoiL people!
