Zelus Triple Threat

We get it. Shopping for insoles is tough. With so many options at your fingertips, how do you pick the right one?

Most insoles are designed for either performance OR medical purposes, but only one is specifically engineered to improve performance AND help prevent injuries AND kick pain to the curb.


Our insoles are strategically designed for healthy feet (and bodies) that would like to remain that way. Sure, you feel good now, but does that mean you should just be content and sit around and wait for a painful problem to arise?

Like getting an oil change for your car; taking preventative measures for your feet will help decrease issues in the future. Plus, our SmartCells Technology offloads up to 20% of the impact force you put in, providing your body an out of this world, next-gen cushioning that your feet will thank you for.


Our insoles are specifically engineered with design elements and materials taken right from a high-class, fully functional orthotic — just like the ones trainers give to their athletes AND doctors give to their patients.

By leveraging the deep orthotic roots of Fastech Labs, we have developed an unmatched off-the-shelf prefab solution to support your feet where they will function best. And when your feet are correctly in place, there is no stopping you from performing at your highest possible level.


Our insoles are constructed with a cushioning system unlike anything else on the planet. There is literally no other insole that has the ability or capability to give you the Zelus level of comfort. It’s all thanks to our patented SmartCells Cushioning.

When you have the best anti-fatigue, impact-absorbing tech in your shoes, to say that your feet will feel amazing would be an understatement. Plus, with our varied and unique lineup of insoles, reaching unmatched levels of pain-reduction has never been easier.

“Hunting is my passion and I’ll do just about anything to get a few more years of mountain time out of my legs. I could definitely feel the difference these Zelus insoles made this fall and I’m looking forward to more advancements from this great company based right here in the Pacific Northwest.”

Rob Endsley
ESPN's The Outdoor Line

“I tried these insoles and they changed my life. As an athlete, the wear and tear on my body eventually catches up with you. These could have been a game changer for me as I got older. I didn’t get as sore in my feet, knees, in my joints. I didn’t expect for them to have that much of an impact. This will be game changing for athletes and allow them to perform longer and perform at their best.”

Jake Heaps
NFL Quarterback - RWQB Director

“He showed me the Zelus insoles and explained the technology to me – crazy thing is after finishing later than 11pm on the last day, everything BUT my feet hurt. Needless to say, I’m a fan.”

Pro Pickleball Player

“I have custom fit $400 orthotics that don’t work nearly as well as these.”

Joel R.
Surgical Sales Manager

“With the evolution of the SmartCells Technology into Zelus insoles, it opens the door for more athletes to stay active, and healthy both on and off the court. I highly recommend Zelus Insoles to any program.”

Coach John Dunning
5x NCAA National Champ - Coach

“After using the Olympus PRO, my feet feel more energized throughout my competitions and my recovery time has been cut in half!”

Tyler Loong
Top 10 Pro Pickleball Player

The first pair I tried is great. They’re responsive and have very little added anything. They’re no frills and flat. This is important to me because I don’t want my feet to feel forced into an unnatural position. After putting hundreds of miles on my legs already in 2017, I really like the stress-reducing design. I’ve worn these in my retired running shoes and my feet have been very happy.

Coach Rachel Running on Happy

“As an avid runner, I was constantly having issues with foot problems. Whether it be shin splints or foot aches they never seemed to go away. Luckily, I was able to try out Zelus Insoles. The majority of my running is outdoor, in all kinds of terrain and the arched foot support and padded toe cells aided my run. I would recommend it to anyone from active sports enthusiasts to someone standing for long periods of time in one spot!”

Taylor H.
Avid Daily Runner

“Playing as many as 4-5 days a week means my feet and joints take a pounding on the pickleball court. I had a few aches and pains starting to arise. Knees, plantar fasciitis, hips all were sore and aching after playing for hours. I found Zelus insoles after extensive searching and was instantly hooked. Not only did the soreness and joint pain go away, I found that my legs and feet weren’t as tired after playing. The support and comfort of these insoles is incredible. I’ve tried many other options and to me, Zelus is by far the best. I would recommend these to anyone needing additional foot support and pain relief.”
