Align your feet, and your whole body transforms.

BEFORE / AFTER

Approximately 80% of Japanese people wear shoes that don't fit their feet.

That misalignment causes pain, fatigue, and poor posture.

People suffering from foot fatigue and pain

Off-the-shelf insoles don't always

fit your feet.

Scan your foot shape!
3 minutes at home!

And instantly transform it into an insole.

This is not just any insole.

It molds to the unique shape of your sole, fitting your arch, heel angle, and foot pressure distribution.

It's a completely custom-made insole that you can create on the spot.

What you really need is an insole perfectly customized to your foot. That's the philosophy of Arch Fit.

ARCH FIT

Why does a foot mold alone

change your body?

The foot is called the "second heart" and is the foundation of the entire body.

When the arch of the foot collapses, that distortion can spread to the knees, hips, and shoulders.

Conversely, if the sole of the foot is properly supported, it has a positive impact on posture, fatigue, and pain.

Arch Fit is designed to allow anyone to apply this principle at home in 3 minutes.

🦴

Principle of Arch Support

Properly supporting the three arches of the foot evenly distributes weight. Reduces stress on joints.

⚖️

Mechanism of Foot Pressure Distribution

Uneven foot pressure creates localized overload, causing pain and fatigue. Custom shapes distribute pressure across the entire surface.

🧠

Postural Chain

Foot → Knee → Pelvis → Spine is a single "postural chain." When the feet are aligned, the upper body also naturally improves.

🔥

Thermoplastic Material Technology

Thermoplastic polymer that softens with hot water and solidifies upon cooling accurately reproduces your foot shape down to the millimeter.

Supports your feet
in every situation.

One insole, suitable for everything from daily life to active pursuits.

CUSTOMER REVIEWS

What users say.

★★★★★

K-san (30s, Track and Field)

My left arch was collapsed, and I had tightness in my Achilles tendon and knee. I bought many off-the-shelf insoles, but none of them worked.

When I wore these customized insoles, I felt my arch muscles working in a way I hadn't before.

I'm glad I bought them.

★★★★★

Y-san (30s, Desk Worker)

I suffered from low arches.

It's great that I can just mold them and put them in my everyday shoes right away.

★★★★★

I-san (20s, Delivery Driver)

The foot grip is completely different.

If my feet are aligned, I feel like my upper body condition will also improve.

HOW TO USE

How to make your insoles.

STEP 01

Pour hot water and
soak for 15 seconds

Pour hot water into the included container.

Place the insole, heel down, into the container and wait for 15 seconds.

The material will soften, making it ready for molding.

STEP 02

Set in the mold and
stand for 2-3 minutes

Remove the insole and place it on the included mold.

Place your foot on the insole and stand straight for 2-3 minutes.

The shape of your sole will be precisely imprinted onto the insole.

※ Standing straight will result in a more accurate foot mold.

STEP 03

Remove and
cool to complete

Remove the insole from the mold and let it cool completely. Once cooled, the molding is complete.

Your unique shape is now fixed.

Then, simply swap it into your everyday shoes.

Sneakers, dress shoes, running shoes—it works with any type of shoe.
