Z-CoiL Footwear is the original spring shoe engineered to relieve severe foot, leg, and back pain. Every Z-CoiL shoe has a patented spring coil under the heel that provides massive cushioning! With active compression over 1 inch, the impact in each step is reduced by 50% over regular shoes. You feel an immediate reduction in pain and pressure in your bones, joints, and muscles. Z-CoiL's also features a built-in rigid orthotic. This contoured orthotic located below your feet resists twisting and isolated pressure points. The result is greater stability, balance, and support, especially when walking on uneven terrain. Z-CoiL's are stable in all conditions, and most people find they get used to the feel and support of Z-CoiL's in just minutes. Last but not least, the rounded forefoot includes nearly an inch of soft cushioning that shields the ball of your foot from excessive strain while assisting with forward motion. Z-CoiL's are a great value typically lasting 2-3 times longer than conventional shoes, saving you money. Over 1 million pairs have been sold since 1995. Try Z-CoiL today and find out why so many people in all walks of life have been able to live pain-free. The most common areas of relief are plantar fasciitis, heel spurs, and back pain, but Z-CoiL is also very effective for sciatica, Morton's neuroma, metatarsalgia, arthritis, diabetic neuropathy, and joint and hip pain. Z-CoiL is not a shoe but equipment that makes walking enjoyable, light and easy. There is no need to sacrifice style for comfort any longer with the Sofia.
