Over-pronation is when your foot rolls inward as you walk. It can be caused by repetitive stress, flat feet, problems with your muscles, or loose ligaments, which can cause your body to get out of alignment. Whatever the cause, all you know is that “over-pronation” can lead to a number of serious problems in the foot, ankle, knee, hip and back.  The diagram below shows a right foot during the normal gain cycle.  There are many ways to correct over-pronation including Z-CoiL® Pain Relief Footwear®

Pronation is essentially the rolling inward of the foot as it comes into contact with the ground through each step.  Pronation is a normal process which spreads the load of ground contact over the muscles and tendons and bones of the lower leg.  Pronation help so slow the impact and protect you body from excessive stress.  However excessive pronation is dangerous because it crease excessive rotation of the leg which repeated in thousands of foot strikes stresses you foot, ankle, leg and back.

Z-CoiLs are uniquely engineered to keep you from feeling the pain caused by over-pronation. The coil under the heel absorbs the jarring shock you feel with each step. And, in less than a minute, you can rotate the coil to adjust to your gait, providing maximum comfort. The rigid foundation gives your feet, and your entire body, the support needed for proper alignment of the joints. The round rocker bottom sole helps you to move forward effortlessly.
