How Long Should Z-CoiLs Last?
On average, Z-CoiL shoes are designed to last 1 to 3 years, depending on your activity level, body weight, and the surfaces you walk on. Many customers find that the shoes themselves outlast traditional footwear—but that doesn’t mean every part should go unchanged indefinitely.
We strongly recommend:
- Replacing coils and insoles every 12–24 months or sooner if you notice changes in support or compression.
- Inspecting your footwear regularly for signs of wear, especially in the coil housing, heel pad, outsole, and any upper materials like Velcro or stitching.
- Retiring shoes that are more than 3 years old, especially if they show signs of stress, loosening, or structural breakdown.
Why Older Z-CoiLs Can Become Unsafe
Over time, materials naturally degrade. The glue that holds components in place may dry out, and plastic or metal parts may weaken after years of absorbing shock. This can lead to failures such as coil separation or strap breakage—especially in older pairs that haven’t been serviced or replaced.
For your safety, we do not recommend wearing Z-CoiLs that are more than 5 years old without a thorough inspection. Even if they still “feel fine,” unseen stress or damage can pose a risk during wear.
Our Recommendation
To keep your Z-CoiLs performing at their best:
- Inspect your shoes every 6 months.
- Replace high-wear parts (coils, insoles) as needed.
- Consider retiring any pair older than 5 years.
