Product Description


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.

    I worked in department of corrections and wore these boots and literally put them through everything from being puked on and stepping in feces and pee the held strong working on the concrete floor and walking almost 10 miles a day and the never flinched I was going to school at the time as well wore from school to work or vice versa I’m also a shad tree mechanic and anything I threw at these boots they held up I recommend these to the working person who is on the feet all the time and have a differential in leg length as I do the individual spring absorbs that impact and never stops………However I will say they aren’t the best looking heel… in fact my friends called them hooker boots because of the heel on them but they were amazingly comfortable……..and the price yeah a little pricey but you do the math I wore everyday for a year I got my money back on them and then some because I don’t see a pair of Jordans keeping up… I hope I have helped you and your decision thanks for reading
