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 Custom Z-Fitters headquarters with any questions @ 888-934-8837
