Here’s what you need to know

Getting Started

With our patented spring coil and built-in orthotic, your Z-CoiLs provide up to 50% impact reduction, making walking and standing on hard surfaces easier than ever. They also return energy with each step, helping you stay energized all day.

Caring For Your Footwear

To keep your Z-CoiLs performing at their best, follow these care tips:

Replace a Worn-Out Coil

If the steel coil wears through the rubber outsole, you can purchase replacement coils here or order by calling 1-800-268-6239. Remember to note the coil’s positioning before removal to install the new coil correctly.

Here's our how-to replace the coil video.

Tighten a Loose Coil

If you notice a clicking sound or feel the coil has become loose, follow these steps:

  • Remove the padded insole.
  • Lift the fabric flap at the heel to access the bolt.
  • Tighten the bolt with a Phillips screwdriver (use firm pressure but avoid stripping the head).
  • Watch the video here

If the “Z-Nut” holding the coil loosens, contact Z-CoiL Customer Service at 1-800-268-6239 for guidance.

Avoid Excessive Heat

Protect your Z-CoiLs by avoiding hot environments like parked cars in the sun. High temperatures can affect materials, especially the forefoot cushioning and Z-Orthotic®.

Clean Your Shoes Regularly

Wipe them down with a cloth dipped in mild, soapy water. For leather models, use a leather cleaner and conditioner to keep them looking like new. Insoles can be gently hand-washed and air-dried for freshness.

Allow Your Shoes to Breathe

Rotate between pairs if possible, giving each set time to air out. This prolongs their lifespan and keeps them feeling fresh.

Our Trial Programs

Your Guarantee

We’re so confident that you’ll love your new Z-CoiLs that we offer two distinct trial programs for your peace of mind. Depending on the type of purchase, you’ll enjoy either our 30-Day Risk Free Trial or our 14-Day Free Trial Program. Here’s how each works:

30-Day Free Trial: All Regular Purchases

With our 30-Day Free Trial, you have a full month to experience Z-CoiL comfort with any regular purchase. Wear your shoes as much as you need during this time—whether you’re walking, working, or exploring—and if they’re not the perfect fit, return them in any condition within 30 days for a hassle-free refund. This trial is available for all orders made through our website, over the phone, or in-store at participating retailers.

14-Day Free Trial: Special Try-It Program

Our 14-Day Free Trial is part of our Special Try-It Program, designed for those who want a shorter trial period to see if Z-CoiL footwear is the right solution. Through this program, you can wear your Z-CoiLs in real-life situations for two weeks, absolutely free. This is a great option for those who are new to Z-CoiL and want a quick, commitment-free way to test our unique comfort and support. If they don’t meet your needs, simply return them within 14 days.

Adjusting Your Z-CoiLs for the Perfect Fit

  • For High Arches

    If you have high arches, consider using the Z-Fit® Custom Arch Insole (sold separately). This insole offers interchangeable arch heights, allowing you to achieve the perfect level of support tailored to your needs.

  • Adjustments for Over-Pronation

    If you over-pronate (ankles roll inward), you may benefit from coil adjustments. Each coil has firmer and softer sides to provide targeted support. Our customer support team is happy to guide you through adjusting your coils for optimal stability.

  • LOW ARCH -This is a physical adjustment to the shoe Z-CoiL Pain Relief Footwear

    Adjusting for Flat Feet

    If you’re finding that the standard arch support feels too high or uncomfortable, please reach out to us for a special adjustment. This adjustment is only recommended for flat or low arches; customers with a regular arch generally benefit from the raised arch that provides balanced support and helps equalize pressure.

  • Turn a Whole Size into a Half Size

    Z-CoiL Footwear is only available in whole sizes. If you typically wear a half size, we suggest going up to the next whole size. Each pair includes a thin foam insert that can be placed beneath the padded insole to create a more precise fit.
