THE PROBLEM

I want to jump higher.
I want to run faster.
But my knees and tendons hurt.

When landing from a jump,

the knees are said to bear more than four times the body weight.
For a 60kg person, this burden can be as much as 240kg.

If this training continues, the knees will not be able to withstand it and will be injured.

Many athletes wear expensive shoes for practice,
but their insoles are worn out, thin, and soft.

There's a limit to what thin, soft insoles can do
to convert ground rebound into propulsion.

Therefore, the truly necessary insole has

①

Knee-protecting cushioning

②

Hard-rebounding properties that
transfer foot power to the ground

An insole that achieves both of these will protect athletes' knees while maximizing their performance.

SOLUTION

Hard-rebound insoles protect your knees and allow you to move faster and higher.

POWER STEP is a sports performance insole that combines high-elasticity PU foam and air cell cushioning.

It not only absorbs the force of impact, but also converts the ground reaction force (GRF) directly into kicking energy. It supports "unbeatable on the ground" play in all sports, including basketball, volleyball, track and field, soccer, and marathon. Available in sizes from 22.5cm to 30.5cm. Unisex.

HIGH REBOUNDHigh Rebound

Returning the force of your step to your next step.

High-elasticity PU foam repels the force of your step as rebound force. Kicking off becomes smoother, allowing you to jump higher and run faster with the same amount of practice.

→Greater rebound when taking off for a jump

→Smoother kick-off for sprints

→Prevents slowdown in the latter half of long-distance runs

AIR CUSHIONAir Cushion

Absorbs shock, keeping you in shape for continued practice.

Built-in air cells distribute landing impact. Reduces stress on knees and lower back during training on concrete or hard surfaces, allowing for longer practice sessions.

→Less knee pain from repeated dashes and landings

→Fewer physical ailments even on hard surfaces

→Improved foot and leg condition after practice

TRUSTED BY ATHLETES

Current athletes have also approved.

Why athletes at the forefront of their sport chose POWER STEP.

ATHLETE 01 — Track and Field / Basketball

Kamui Koyama (37)

When doing approach jumps or vertical jumps, I used to use off-the-shelf insoles, and my knees would always hurt after practice.

After using these insoles, the knee pain was significantly relieved even with the same amount of practice.

I can feel the strong push off the ground and the rebound that comes back. I'm currently using them more for knee protection than for improving my records.

ATHLETE 02 — Street Workout

Kazuto Sudo

Street Workout Japan National Team Member

When I do tricks like backflips and other spinning jumps outdoors, it's easy to get good height.

ATHLETE 03 — Street Workout

Hideki Nakatani

Street Workout Japan National Champion

The impact on my knees when landing has been greatly reduced.

I had knee pain and was unconsciously protecting it when pushing off or landing, but now my anxiety has decreased a little.

PERFORMANCE SCENES

Dominating the ground in any sport.

POWER STEP is not limited by sport.

Jumping high, running fast, sustaining for longer - it forms the foundation of all movements.

JUMP

Basketball・Volleyball

Spikes, rebounds, blocks. Generates maximum rebound the moment you push off, creating a 0.1 second difference on the court.

SPRINT

Track and Field・Soccer

Start dashes, quick changes of direction. The gap widens with every kick, unleashing acceleration that leaves opponents behind on the field.

Tennis・Rugby・American Football

Tackles, drives, scrums. In contact sports where large impacts are repeated, stability at the feet determines the outcome.

RUNNING

Marathon・Long Distance

Shock absorption reduces stress on knees and lower back, curbing fatigue and pushing you to the finish line. The difference is made in the last 1km of a 42.195km race.

ATHLETE REVIEWS

Voices of athletes who have used it.

★★★★★

Kanta Ishikawa (26, Soccer)

I play soccer and have tried various insoles, but I think this insole will make pushing off and changing direction smoother. I also have a job where I walk a lot, so wearing these helps reduce the strain on my knees.

★★★★★

Yuki Taguchi (53, Japanese Kempo)

I injured my knee ligament a long time ago, so I can't push myself too hard, but when I jump and land with these on, the impact is absorbed and there's less strain on my knees.

★★★★★

Andreu (27, Skateboard)

Actually, in skateboarding, there are many tricks where you jump and rotate the board, so jumping power is super important. With these insoles, I feel a stronger rebound from the ground when I jump compared to regular insoles!

Popular even overseas!

THE SCIENCE

Why does performance improve?

From the perspective of sports mechanics, we explain why POWER STEP delivers results.

01 — Maximizing Ground Reaction Force (GRF)

High-elasticity PU foam absorbs and releases the force of impact, pushing the body up as rebound force when kicking off. With every step, energy is efficiently converted into propulsion.

02 — Spring Effect from Air Cells

Built-in air cells distribute landing impact while storing energy. This shortens the time between landing from a jump and the next take-off, allowing for continuous movement.

03 — Arch Support for Body Axis Stability

Supporting the arch of the foot suppresses body axis deviation. Propulsion is transmitted linearly, ensuring that sprints and jumps remain stable and on axis.

04 — ORXINLITE Patented Breathable Material

The patented breathable, sweat-absorbing, and antibacterial material keeps the internal foot environment comfortable during intense exercise, allowing for sustained focus during long play.

MATERIAL & TECHNOLOGY
