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. The outsole has a thick off-road tread that holds up well in harsh environments. This is our longest lasting outsole design. 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 a Z-CoiL Dealer or 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). Any coil adjustment will add more resistance to the inside of the foot which helps to keep the foot level if you over-pronate.
