1. This 1.0 part fits all Korean made Z-CoiL Product. If you are not sure this part will fit your shoe – please reference your shoe label to see where it was manufactured.
2. Slip resistant outsole – helps to prevent slipping on water. The outsole has fiber mesh embedded into the rubber for added strength.
How to Replace:
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. Use caution not to strip the screw.
Step 3. Re-attach the spring in EXACTLY the same orientation as the old spring. Tighten as much as you can without stripping the screw. 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 over pronation.
Step 4. Call the Z-CoiL headquarters with any questions @ 800.268.6239
Over – Pronation adjustment:
All Z-CoiL springs can be adjusted for over-pronation (feet that roll too far inward). We recommend visiting a dealer if you are are unsure about pronation.
To adjust for more severe pronation switch the left coil to the right shoe and vise-versa. For moderate pronation you can rotate the coils 90 degrees (left foot counterclockwise and right foot clockwise). Click here for a reference guide. Any coil adjustment will add more resistance to the inside of the foot which helps to keep the foot level if you over-pronate.
