Only HIRONOBA EXERCISE and YOSHIRO SOCKS can provide tremendous tread strength!

When you stumble or trip while standing or walking, you can prevent yourself from falling by stepping on your toes, because the power and function of the toes are working well. If the toes are not working properly, the person will not be able to step on them and the risk of falling will increase. Standing and walking with poor posture without being able to stand on one's feet can cause excessive stress on the knees and hips, leading to knee pain and lower back pain. HIRONOBA EXERCISE and YOSHIRO SOCKS can improve the ability to stand on one's feet in a surprisingly easy way.

Toe deformityNo. 1 improvement rate!

Strong support for big toe, small toe, and floating toe
State-of-the-art fibers and construction!

Slip resistant

The surface area of the yarn used in these socks reaches several times that of normal surface yarn. As a result, a large frictional force is generated both inside and outside the sock, so that the foot does not slip and floating toes, bent toes, and big toes can be prevented or improved.


The special manufacturing technology and the power of the stretchable fibers are made to fit any toe deformity shape, and the tension of the threads causes the foot to return to its original shape, thereby gently improving toe deformity.


They are more than 9 times sturdier than regular socks. The pass line in general abrasion tests is 500 times or more, and even major brands are tested 1,000 times, but YOSHIRO SOCKS have passed abrasion tests of 9,000 times or more.

She overcame two ovariectomies and conceived her second child naturally!

HIRONOVA EXERCISE and YOSHIRO SOCKS were born out of a desperate attempt to improve my wife's O-legs. After overcoming bilateral ovarian tumors and two ovarioectomies, she became pregnant naturally with their second child at the age of 39. We hope that this story of how my wife, who was told that pregnancy was impossible, gave birth to a miracle child without fertility treatment will be a beacon of hope for as many people as possible.

Frequently Asked Questions

Is the treatment of hallux valgus painful?

It is basically painless, although it can be a little painful depending on the symptoms.

Is it possible to have a condition other than hallux valgus?

In addition to bunions, our clinic is also used by patients with various other conditions such as osteoarthritis of the knee and herniated discs.

Can the big toe be cured because it is genetic?

Although the skeletal structure is inherited, the cause of hallux valgus is mostly environmental factors such as shoe wear and muscle imbalance.

I was told at the hospital that surgery is the only way to improve my pain.

We have non-surgical treatments for severe bunions to improve pain.

I have floating toes, flexed toes, and a high instep. I am particularly concerned about the high instep. Is it still difficult to correct them if I am already an adult?

Correction can be done at any age, although the length of time required for correction depends on the shape and hardness of the foot.

I also have foot pain and want to do something about it. Is there any self-care for high instep that I can do by myself, at least a little?

Basically, try to do "HIRONOBA EXERCISE" for at least 10 minutes every day. When walking, choose appropriate shoes and try walking with "YOSIHRO SOCKS".
