Z-CoiL, CoiL Enclosed Black Slip Resistant
- Ships as a pair
- Slip-resistant tread design - helps increase traction on slick surfaces.
- The soft spring enclosure will last 1-2 years under normal dry conditions, however, it will age prematurely when exposed to strong chemicals (used mainly in cleaning agents) or animal urine.
- Embedded mesh fiber - for added strength
Step 1. Remove the insole from each shoe.
Step 2. Below the insole is a “trap door.” Lift up the door and unscrew the spring with a Phillips screwdriver. Tighten firmly, but use caution not to strip the screw head.
Step 3. Re-attach the spring in EXACTLY the same orientation as the old spring. Note: Z-CoiL springs can be adjusted in 90-degree increments to adjust for pronation. Turning the coil will affect the resistance on the inside/outside of your feet and may cause under or overpronation.
Step 4. Call the Custom Z-Fitter headquarters with any questions @ 888-934-8837
