How Z-CoiL’s Patented Technology Works
Z-CoiL® Pain Relief Footwear®’s revolutionary technology isn’t really revolutionary at all. It’s evolutionary. It’s engineered to help you stride the way the human body was designed to, in an environment that the human body was not designed for.
Gait Cycle and the Kinetic Chain
Humans propel themselves through the concrete jungle the same way they have for thousands of years: heel strike → full forefoot load → heel lift → toe off. During a normal gait cycle, your heel makes contact and immediately redistributes the force—twice your body weight on each foot—up along the side of your foot, the part of your foot designed to actually absorb impact and transfer energy to continue forward motion.
However, not all impact is transferred up your foot. Much energy is transferred along what chiropractors call the kinetic chain: heels → ankles → shins → knees → thighs → hips → pelvic girdle/lower back.
Unlike the environments our ancestors walked, today’s concrete and other hard surfaces are much less forgiving, resulting in significantly more stress to the body. Every day we experience thousands of collisions with the ground. The greater impact delivered up the kinetic chain, sometimes exacerbated by an improper gait cycle (over-pronation or supination), compromise the human body’s ability to absorb and redistribute stress forces, causing injuries.
Impact Reduction, Stability and the Problem with Modern Footwear
Preventing stress injury and providing relief for existing injuries requires impact reduction—i.e., footwear that actually limits the amount of force that travels up the kinetic chain. However, cushioning impact alone will not ensure healthy joints and pain relief. Shoes that offer a lot of padding actually encourage atrophy in the muscles of the foot. Weak muscles can lead to a number of compensating movements, many of which direct stress forces to areas of the foot that are not designed to absorb impact.
Unfortunately, most modern footwear has taken an either-or approach to solving the problem of increased impact along the kinetic chain. Either they provide cushiony soles to reduce the force of impact but allow the flexibility for soft tissues to move outside a normal range of motion, or they provide a rigid sole to keep the foot (and stress forces) in a natural range of motion but with very little impact-absorption, resulting in high impact all the way up the kinetic chain.
The Z-CoiL Solution
Z-CoiL Pain Relief Footwear is the only shoe that offers both the impact reduction and stability you need for pain relief, injury prevention and whole body support. Z-CoiL shoes have the:
Patented conical spring in the heel, which reduces impact by 40-60% (according to tests performed by the American Department of Energy) and provides energy return, reducing fatigue.
Patented Z-Orthotic™ to stabilize tendons and ligaments.
Rocker bottom sole that assists forward motion and limits movement during toe-off.
Flex line at the forefront of the foot to encourage bending at the ball of the foot.
Extra wide toe box to relieve pressure on toe joints.
All elements of our shoe design provide Z-CoiL treatment—effective pain relief from a number of lower body impact-induced conditions.
