THE ULTIMATE PERFORMANCE GEAR
One step beyond
your limit.
Trusted by Japan national team athletes and B.League pros.
Adopted by Inter-High champion schools.
High-performance gear that supports your posture from the ground up.
BRAKING
Don’t push off the ball of your foot.
That’s a “brake.”
The “ball-of-foot theory” that so many athletes believe in.
Anatomically, it engages the very muscles that stop movement.
Pressing the accelerator and the brake at the same time
costs you performance and can place excessive strain on your body.
Three approaches
that rewire your instincts.
Physical stimulus
The body responds to physical stimuli picked up by the sensors in the sole of the foot. By approaching the sole correctly, it supports balanced, natural posture.
Heel stabilization
Rather than forcing the arch upward, a proprietary raised structure stabilizes how the heel meets the ground. The result is an environment where every toe can grip the surface more readily.
Lightweight design
However advanced the function, weight that drags down performance defeats the purpose. Engineered to the limit of lightness so it never interferes with sharp steps or jumps.

Turn your effort into 100% output.
A high-performance insole that targets the postural breakdown caused by over-reliance on the ball of the foot, physically supporting the arch and how your foot meets the ground.

DEVELOPER STORY
A body specialist’s search led to
1 answer.
It isn’t a lack of talent. More often, the posture that forms your body’s foundation has broken down.
I’ve coached more than 10,000 athletes across Japan and led a team to a national runner-up finish at the junior high level. Throughout, I kept running into an unfair reality: the harder an athlete works, the more strain they place on their body.
To break that deadlock, I spent two years and no small amount of stubbornness bringing this insole to completion. It isn’t just something you slip inside a shoe. It’s support gear built to connect your effort to results.

“My peak jump height feels different.”
I used to feel power leaking away at the moment I took off. Now it feels like I go straight up. I’d be nervous playing without them.

“For my son, who’d started skipping practice.”
He was missing sessions, so we bought a pair. Since he started using them he says there’s less discomfort when he plants his foot, and he can play at full effort again.
K.T., parent of a 14-year-old (basketball)
“I stopped losing contact battles.”
Older teammates used to shove me off the ball straight away. With these in, my core somehow stopped wobbling and I can hold my ground under the basket.

FAQ
Questions from parents
Yes. They can be used from around age six (size SS and up). The growing years are exactly when it matters most to use the toes properly and build an awareness of good postural foundations, which is why sports teams across Japan have adopted them.
They can be used. Making the toes easier to engage may help distribute impact during movement.
This product is not a medical device and is not intended to diagnose, treat or prevent any condition. If pain is significant, please consult a doctor.
Because you trim the toe end to fit, growth of roughly 0.5–1 cm (about a quarter to a half inch) can be absorbed without replacing them. Once the heel position starts to sit incorrectly, we recommend moving up a size so the support works as intended.
Function and features
Rather than propping up the arch from below as conventional products do, this is a proprietary design that stabilizes how the heel meets the ground and makes the toes easier to engage. The underlying design philosophy — drawing out the foot’s own potential — is fundamentally different.
Many people notice the stability and fit the moment they put them on. For changes during play, one to two weeks up to a month is a rough guide.
These are individual impressions and results are not guaranteed.
Sizing, durability and price
We recommend replacing them four to six months after you start using them.
That is only a guide, however, and will shift depending on how often and how hard you use them, and how they are stored.
If you notice any of the following, we suggest replacing them early regardless of how long you have had them.
• The cushioning feels thin or flattened
• Visible wear or tearing on the surface
These are not simple shoe liners but performance support gear that condenses a professional coach’s method. Spread across a four-to-six-month replacement cycle, the daily cost is small, and we believe it compares well against what athletes routinely spend on conditioning.
