NEXT GENERATION INSOLE
Your game changes
from the heel.
You don't have to believe it.
First, watch this video.
There's a video that has been
viewed over 1 million times on social media.
Just by putting it in their shoes,
they become able to withstand the power of a 2-meter tall athlete.
"That's a lie!! It must be staged!"
The comments section was filled with such voices. But this is actually happening.
This is the result of trying it with hundreds of athletes in high schools and teams across the country.
Why is this happening?
I will explain the reason now.

Custom Insoles
vs
TOP PERFORMER
When Miyamoto held custom insoles, he stumbled when pushed from the side.
The moment he switched to TOP PERFORMER, he didn't budge even when pushed hard.
"Seriously!? How?
I can push back!"
A Japan high school national team player,
When pushed with another insole that looked good, his posture collapsed.
On TOP PERFORMER, he pushed back even when pushed.
"Really?! Why?
I can push back!"
This change happens just by standing barefoot.
The change that the athletes in the video felt,
can be yours too.

We conducted multiple physical ability tests comparing with and without TOP PERFORMER insoles,
and confirmed performance improvement in many areas.
According to our research (N=20)
Design Concept
This isn't "guts" or
"staged".
The structural design of the sole
was the key.
The sole of the human foot is densely packed with sensory receptors that affect the entire body's posture. TOP PERFORMER is an insole designed to leverage this sensation in the sole.
Unique structure for stabilizing
heel contact.
You don't need to be conscious of it. Just by wearing it,
the design starts to change your foot sensation.
Structure that minimizes power loss when kicking off
The design stabilizes the heel's contact position, creating a structure that prevents energy loss during kick-off. It supports quick and sharp movements.
Design that stabilizes the heel's contact position
The convex shape of the heel stabilizes the contact position, making it easier to maintain posture. It supports stability during physical contact.
Supports natural movement from the sole to the core
The design allows for smooth weight transfer from the heel to the ball of the foot. It supports movements that utilize the entire sole of the foot.
How you use your "heel"
can change your movement this much.
Skill therapist Takahashi explains based on his experience with over
10,000 athletes.
The first step of a drive (1-on-1)
Leaning forward, accelerating after braking
Trying to move after "braking" with the ball of the foot (base of the big toe). Toes are lifted, not gripping the ground.
Heel is engaged, 5 toes grip the ground
With firm weight on the heel, the 5 previously lifted toes "grip" the ground and begin to function.
Aerial Battle (Rebound / Jump)
Knees turn inward during takeoff, losing power
At the moment of takeoff, the knees turn inward (knee valgus), and the force used to push off the ground is lost laterally.
Heel and toes are more likely to align and work together
Designed to stabilize the heel, making it easier for the entire sole of the foot to work in conjunction. This helps maintain body alignment and allows for a straighter upward push.
Physical Contact (Pushing)
Toes-focused, unstable base
With weight concentrated on the toes, the body's base is unstable. Even with core training, it's hard to exert force when the base is shaky.
Heel is stable, making it easier to maintain a stable posture
Designed to stabilize the heel, making it easier for the pelvis and spine to align correctly, and for the arch to form naturally.

Voices of players who
have used it.
"After using it for just 1 week, I feel a difference in the fit of my feet."
3rd year junior high school student, basketball club (Tokyo)
"The feeling in my feet after practice is clearly different. I didn't think an insole could make such a difference."
2nd year high school student, basketball club (Osaka)
"My feet feel more stable, and it's easier to concentrate on my movements on the court."
3rd year high school student, basketball club (Fukuoka)
"My son started using them before the Inter-High, and he said himself that the 'feeling in his feet changed'."

SoccerWhy I created this insole.
Coming earlier than anyone else, staying later than anyone else. All the effort accumulated while pushing my body to its limits was dismissed with a single word: "talent," "physique," or "instinct."
The harder I worked, the more tired I became. The more I practiced, the more my body broke down. Yet, I always felt a sense of unease in a world that told me, "try harder."
In particular, it was quite painful when I met a child who had worked incredibly hard but had to leave their sport due to a major injury. I wondered if there wasn't a way to help them earlier, or in a different way.
It's not that they're not trying hard enough.
It's that their effort isn't reaching their bodies.
I consulted with my deeply respected mentor. The response I received was, "An insole approach might work."
It started with cutting the insoles that came with shoes with scissors. I tried and failed. I remade and failed. Before I knew it, two years had passed in this trial-and-error period.
I want them to experience the joy of playing again, feeling sensations like "it's easier to grip the ground," "my feet feel stable," "my movements are smoother," and "the fit is great."
So that their efforts don't go to waste. So that the time they've put in isn't pointless. I created TOP PERFORMER to help them build a body that can believe in themselves again.

Feelings of movement begin to change
This is the period when many athletes feel "my movements feel smoother" and "my feet have become more stable."
Feel a sense of progress in your play
Some even report teammates saying, "Your movements have changed lately."
"Completely different from before"
This is the period when the stability of your feet becomes established, and you start to feel more relaxed in your overall play.
※ Individual results and duration of change may vary. Continued use is recommended.

Frequently Asked Questions
Q
Is the video staged?
It is not staged. The design, which provides appropriate stimulation to the sensory receptors on the sole of the foot, causes a change in postural stability. This is the result of trials with hundreds of athletes in high schools and teams nationwide.
Q
How is it different from other insoles?
Traditional insoles are primarily designed to "support the arch with shape." TOP PERFORMER is based on a different design philosophy: "stabilizing the heel contact point and utilizing the sensation of the sole of the foot."
Q
Why doesn't the insole have an arch?
Actually, the reason the foot's arch disappears is because the foot can't make a 'fist' with its toes. (Just moving your toes isn't enough.)
While there are insoles that artificially create this, our belief is that they don't solve the fundamental problem.
With Top Performer, the heel's skin reaction improves toe movement, allowing for unconscious 'fist-making' with the toes. This is a complex topic, but it's the effect of skin reaction.
To understand this fully, there's too much to write here, so please read our blog.
Q
How long does it take to feel a difference?
There are individual differences, but some people feel a change in their foot sensation within 1 to 2 weeks. For changes in play, please allow about 1 month.
Q
I have foot pain, can I use it?
If you have any medical conditions, please consult your doctor before use. This product is not a medical device.
Q
Can I use them for sports other than basketball?
Yes. They are compatible with all sports, including volleyball, soccer, and track and field, and can also be used for everyday wear.
Q
I can move pretty well now. Can I get even better?
Many users tell us that the improved stability underfoot changes how they feel about their play. This product is especially recommended for those who are not satisfied with their current performance.
Q
What is the minimum age for use?
We recommend ages 6 and up. Many parents purchase these for their children.
Q
How often should I replace them?
We recommend replacing insoles every 4-6 months from the start of use.
However, this is just a guideline, and the actual lifespan may vary depending on the frequency and intensity of use, as well as storage methods.
If you notice any of the following signs, we recommend replacing them sooner:
・Reduced cushioning or feeling of flattening
・Noticeable wear or tearing on the surface
Q
What if the size doesn't fit?
Choose from 5 sizes (SS to LL) and cut to fit your shoes. For cutting instructions, please see here. If you're unsure about sizing, feel free to contact us.
