Z-Liner Vs. Competitor’s Foam Pt2.

The first response video we made, we used their thin insole as its thickness is more comparable to ours. We knew this competitor would try to downplay our video by saying we used their thin insole which set things up perfectly to call them out even further, this time using their thick insole which is nearly 2x as thick as ours and produces the same outcome as the thin one.
Their "lab tests" are also misleading. Dropping on an uncompressed foam insole is irrelevant and does not represent the constant pressure that a human puts on it throughout each day. Their foam compresses
SIGNIFICANTLY with body weight and renders their "lab tests" all but useless which is why the bowling ball hitting their compressed insole is extremely loud and bounces exponentially higher. Their insoles do not work as advertised and it's time for people to know the truth.

DEBUNKING A COMPETITOR’S FOAM INSOLE

This is what the competitor doesn’t want you to know as it jeopardizes the entire premise of their company and products.

The competitor’s cinderblock test videos are real but are also misleading if you consider real life application. If you drop it from high enough, the cinderblock breaks with our insoles and theirs as well, they just won't admit it. Their insole is made of a foam and when you apply the weight of the average human, it flattens out. This flattening changes the outcome, causing the cinderblock to break in this video.

Their insole expands back after ~10-15 seconds but when you’re wearing them throughout the day, they don’t have that time to return to their original state, thus they remain compressed and naturally do not live up to the claims. This video shows the 100% truth of how they respond while you’re wearing them.

We’ve tried to keep it cordial for over a year but they insist on antagonizing everybody including us so the only option we’re left with is to show you their product for what it really is.

You may have seen their videos and they claim bounce is bad but their insoles bounce after you compress them with normal body weight. They’re preaching something while their product does the opposite.

You can walk on our insoles but you won’t walk on us.

Z-Liner insoles are the real deal. Beware of misleading videos by competitors. We guarantee these are the best insoles you’ve tried or your money back. Simple as that.

Z-Liners are proven to help reduce and/or eliminate nagging joint pains. They’re made using a synthetic rubber which is one of the best surfaces to move on. They provide great shock absorption and ample energy all while giving you a true custom fit. They work much differently than foam insoles which are known to flatten out, further reducing their claimed shock absorption. The last thing you want is a foam insole that robs you of your energy.

Energy return is a hot topic and all major footwear companies are in a race to create the most energy returning material. Adidas’ Boostfoam being a prime example which also provides great shock absorption and energy return.

It usually depends on the shoes you’re placing the insoles into. In running shoes, they’ll give a feeling of increased bounce and in applications such as motocross boots that use a stiff shock deadening outsole, they’ll give you the much needed comfort and dampening your feet are looking for.

Z-Liners make the ideal pair for any situation you throw at them. We guarantee it or your money back.

Say no to foam insoles. Once you apply body weight, the foam compresses and loses a large portion of its material thickness, which reduces the shock absorption and over all comfort of the insole.

We have seen incredibly misleading tests using uncompressed foam which doesn’t apply to real world application at all, as humans weigh hundreds of pounds and stand on our feet for hours at a time, further compressing the foam and it’s overall effectiveness.

This is why we chose a synthetic rubber when designing Z-Liners nearly 10 years ago. They’re able to provide great shock absorption, ample energy return while also providing solid yet comfortable base using the Hexcore material which gives the wearer a custom fit by simply wearing them for a few days.

One of the best surfaces to walk/run on are synthetic rubber tracks. They are extremely popular and if you go to your local high school track, there’s a good chance it is synthetic rubber.

Energy returning material is everywhere and for good reason. It reduces shock, gives ample energy return and is known to reduce impact related injuries of the joints by 50%. Every major shoe company is trying to increase energy return in their footwear as much as possible. Adidas, Nike, Hoka, Brooks, ON, Puma, the list goes on and on.

Z-Liners are also made from synthetic rubber and give the wearer significant shock absorption while also providing great energy return rather than taking it all away.

We are confident Z-Liners are the most comfortable insoles you’ll ever try. We offer a 30 day test period. If they don’t suit your needs for any reason, you can return for a full refund. Link in bio.

The courts used in the NBA feature a cushioning material below the hardwood that allows for increased shock absorption and ideal energy return. The last thing you want is a material that absorbs too much of your energy. Too much absorption means that players don’t get as much energy returned to them, and the less energy returned, the harder it is to walk/run/jump. Similar to running on sand or in water.

Energy return is crucial and is a major focus in several industries like footwear (ex. Adidas Boostfoam) along the boom in synthetic rubber tracks that are mainly seen around football fields. These tracks provide great shock absorption and make running more efficient, while also reducing the risk of impact-related joint injuries. Z-Liners are made from a synthetic rubber and provide your feet with an ideal foundation.
