■ List of features (functional details)
[Feature 1] 3D tabi socks
The three-dimensional structure eliminates seams between the toes, and the high elasticity makes them less likely to cause pain. The freedom of the thumb allows for better support, making them easier to wear than five-finger socks. The stimulation between the toes can also help alleviate cold feet.
[Feature 2] Heel support (heel lock knitting)
It reduces ankle wobble and maintains a stable posture. It is also recommended for athletes who tend to sprain their ankles or those with concerns about their ankles or knees.
[Feature 3] Arch cross support (design registered)
The cross arch taping structure firmly supports the arch of the foot, helping you maintain a steady run even in the latter half of the race when fatigue sets in. It supports the core of the body from growing children to veteran runners.
[Feature 4] Thick sole cushion (patented technology)
The special cushioning knit provides double the shock absorption effect and 10 times the durability. It feels like you're wearing an insole, and provides firm protection for the soles of your feet, which are subject to a lot of strain.
[Feature 5] Braided anti-slip
Rubber thread is woven into the ball of the foot to reduce slipping inside shoes and on flooring. Suitable for both gymnastics and everyday use.
[Feature 6] Pile reinforcement on the toe and heel
By using pile knitting in areas that are subject to high impact, durability is increased, making it safe for long-term use.
[Feature 7] Moisture-wicking, quick-drying, antibacterial, and deodorizing
Made with acrylic cotton blend yarn, it quickly absorbs and releases sweat and moisture. Its antibacterial and deodorizing properties keep you clean and comfortable even after practice.

■ Message from the Factory Manager
"You can make the support stronger, but too much tightness makes them difficult to wear and uncomfortable. The important thing is to protect your feet without compromising performance. When you try them on, the feeling of support isn't strong, but you can see a definite change in bending and pushing tests. I recommend them for mini-basketball players who are still growing and whose arches are still developing, as well as veteran players who have suffered injuries, and for recovery purposes."

■ Summary
These high-performance socks not only support athletic performance, but also help maintain leg and hip stability and health in everyday life. They're suitable for a wide range of activities, from intense sports like basketball and tennis to walking, standing jobs, and even senior health support. You'll feel the difference the moment you put them on, so be sure to try these reliable socks. They also make a great gift for Mother's Day, Father's Day, birthdays, get-well wishes, and more.

足袋ソックスを履くと、足の指にほんとに力が入りやすくなるようです!
プレイにも力強さが出ています!
他の足袋ソックスと変わらない、サポーター力が強くキツイです。
以前から足袋ソックス愛用者です。こちらのデザインも2足目です。普段黒てワンポイントは、審判やマラソンの時、こちらのデザインは普段着用です。すねの真ん中まで来て欲しいので星4個にしました。履き心地さいこー。足の疲れが取れやすいのでリカバリーにも向いてます
腰痛が長引く中足元からもアプローチしようと思い購入しました。まだそれ程実感は有りませんが、少し歩き易くなったかな😅
凄く良いです❗️
また買いたい❗️
しかし
もう一足欲しいけど、金額が高い🥲
親指小指あたりの縫い目が少しあたる時があってスレたりして痛くなりそうで気になる😓

FAQ
About TabiSocks
★Feature 1★ Tabi-style support socks
A first for basketball?

The 3D construction means there are no seams between the fingers, allowing the fabric to stretch and preventing pain between the toes.
Apparently, this technology is surprisingly rare, and in sports such as marathons where stress is placed in the same direction for long periods of time, wearing socks with seams between the toes can result in bloody spaces between the toes.
In basketball, the player frequently kicks sideways and braces himself, making it difficult to predict how much strain will be placed on the foot. For this reason, we have adopted tabi-style socks that allow the player to brace themselves firmly without putting too much strain on the toes.
Regular use of tabi-style socks is thought to have the effect of naturally strengthening the sensation in your toes, so we encourage you to move beyond your prejudice and take a step into the world of tabi socks.
*Effects may vary from person to person.
★Feature 2★ Heel support (heel lock)
Securely fasten to prevent injury

Basketball is a sport in which many players suffer from foot injuries such as sprains and knee injuries, but I think there are many players who end up with unstable ankles due to excessive ankle sprains.
When such athletes wear these socks, they may notice that their heels are gently supported.
By providing support to the heel, it is possible to reduce wobbling when landing, and the synergistic effect with the arch support described below is expected to also reduce fatigue.
*Effects may vary from person to person.
★Feature 3★Arch cross support
Not too tight and not too loose

"Too much support can actually lead to a lower arch."
If you rely too much on support, you won't need to use this part of your body, and your muscles will weaken and become unable to be used. On the other hand, if you don't have any support at all, they will remain unable to be used.
Therefore, we have made arch support "necessary" and "minimum" so that players can train their own arches.
Along with heel support, the cross arch supports the shoes, providing a secure and comfortable fit.
However, because they don't feel too tight, you can play for long periods of time without feeling any pain or discomfort. (Naturally, they are also recommended for everyday wear and other sports.)
*Effects may vary from person to person.
★Feature 4★ Braided anti-slip
Fasten your feet and socks, socks and shoes

When we first started making it, we had a prototype stick-on anti-slip mat made and tested it, as it was said that stick-on anti-slip mats are effective for sports.
When I tried them on for practice, I found that the anti-slip coating was very strong and provided excellent grip.
but····
It's true that the shoes and socks don't slip, but because the grip is so strong , I felt like the socks and the soles of my feet were slipping, which really bothered me.
I was very bothered by the feeling of my socks slipping off the soles of my feet, so this time I decided to try adding a knitted anti-slip material to increase the coefficient of friction between my feet, socks, and shoes.
It was the first time I realized that there is a difference in the "sense of stopping" between sports played on sand or grass and sports played on a floor court, and it was a learning experience for me.
I feel that there is still room for improvement in this anti-slip feature.
*Effects may vary from person to person.
★Feature 5★ Foot cushion
Special weaving method achieves twice the shock absorption of conventional products

When you get it, first turn it over.
You will surely see an amazing sight!
You will be amazed at the amount of layers of yarn used on this cushion back.
It provides twice the shock absorption of conventional pile knitting.
The appearance is astonishing, but the comfort is also excellent, and you can feel the amazing technology developed through Econoleg's research and attention to detail in the socks.
This technology allows us to add cushioning where it's needed, without making the socks themselves thicker.
I would like you to try them out and experience the difference in comfort and support compared to sports socks, which are made thicker overall.
*Effects may vary from person to person.
About sock sizes
If you are unsure about the size, we generally recommend going for the smaller size.
For people with a height of 22cm, use 20-22.
For people with 25cm, 22-25
My shoe size is 27.5, but 27-29 socks from other companies are too big, so I wear 25-27... (In this case, I recommend 25-27 socks as well.)
If you wish to sell wholesale
We will only discuss wholesale sales with those who own stores such as chiropractic clinics, osteopathic clinics, salons, etc.
We are looking for people who have tried our products and would like their patients to try them too.
