Z-CoiL, the original spring shoes featured on Shark Tank, made a powerful impression during Season 17, Episode 1. Known for our once-patented steel coil technology, Z-CoiL introduced millions of viewers to footwear designed to reduce impact and relieve pain.
Since airing, the response to our coil shoes from Shark Tank has been overwhelming — and we’re just getting started.
Z-CoiL on Shark Tank: The Spring Shoes That Stood Out
During the episode, Z-CoiL presented its innovative spring-heeled footwear to the Sharks, asking for $250,000 for 10% equity.
Our coil system — often described as “shoes with springs on the bottom” — immediately captured attention. When the Sharks tried them on, the impact reduction and energy return were clear.
Unlike traditional cushioned shoes, Z-CoiL spring shoes:
- Reduce impact by up to 50%
- Feature a once-patented steel coil in the heel
- Include a built-in Z-Orthotic® for pressure distribution
- Use a rocker bottom to assist forward motion
- Provide long-lasting durability with replaceable coils
After tough questions about growth history and scaling, Z-CoiL made a deal on air with Lori Greiner — marking a major turning point for the company.

What Happened After Z-CoiL’s Shark Tank Appearance?
Since appearing on Shark Tank, Z-CoiL has experienced:
- A surge in website traffic
- Increased online sales
- Significant growth in first-time buyers
- Expanded interest from retail and occupational partners
- Rapid growth across social media platforms
Many customers searching for “spring shoes Shark Tank” discovered Z-CoiL for the first time — and thousands decided to try the technology themselves.

Why Z-CoiL Coil Shoes Are Different
Not all cushioned footwear is created equal.
Traditional foam shoes compress and lose energy over time. Z-CoiL’s steel coil system absorbs shock and returns energy with every step. The result is reduced strain on:
- Knees
- Hips
- Lower back
- Feet
This is why healthcare professionals, warehouse workers, teachers, and construction crews make up a large portion of our customer base.
For professionals on their feet 8–12 hours per day, impact reduction isn’t a luxury — it’s essential.
Addressing the “30-Year” Question from Shark Tank
One topic discussed on Shark Tank was our longevity.
Yes, Z-CoiL has been in business for decades.
But longevity means:
- Proven technology
- Hundreds of thousands of customers
- Consistent testimonials reporting real pain relief
Trends come and go. Proven biomechanics do not.
Our appearance on Shark Tank introduced the next generation to a product that has already helped people walk longer and stand longer for years.
