1. This 1.0 enclosed coil fits all Korea 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.
3. The soft spring enclosure will last 1-2 years under normal conditions, however it will age prematurely when exposed to strong chemicals (used mainly in cleaning agents) or animal urine.
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. Install the left “L” spring on the left shoe, and the right “R” spring on the right shoe.
Step 3. Tighten as much as you can without stripping the screw. Note: Z-CoiL enclosed springs can swapped to adjust for pronation. Swapping the enclosed coils will affect the resistance on the inside/outside of your feet and may cause under or over pronation. See “Pronation adjustment” below.
Step 4. Call the Z-CoiL headquarters with any questions @ 800.268.6239
Over – Pronation adjustment:
To adjust for over pronation, switch the left coil to the right shoe and vise-versa. This will add more resistance to the inside of the foot which helps to keep the foot level if you pronate. We recommend visiting a dealer if you are are unsure about pronation.
