The soft spring enclosure will last 1-2 years under normal dry conditions, however it will age prematurely when exposed to strong chemicals (used mainly in cleaning agents) or animal urine.

Embedded mesh fiber - for added strength just like a car tyre.
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.
Contact Springy Feet with any questions.
Over – Pronation adjustment:
To adjust for over pronation, switch the left coil to the right shoe and vice-versa. This will add more resistance to the inside of the foot which helps to keep the foot level if you pronate.
