Hello, this is OLENO, a company that has been researching socks for over 90 years.

This may seem sudden, but for all of you who enjoy running, do you pay attention to the gear you wear on your feet? Many people pay attention to the choice of shoes, but socks also have a big impact on running performance. In particular, five-toe socks have been attracting attention in the running world in recent years. We believe that the benefits of these socks are immeasurable for both road running and trail running.

We are sock developers and runners (mostly trail running). As users, we would like to explain the features of five-toed socks, why they are beneficial for running, and the appeal of the highly durable, highly grippy, and highly moisture-wicking five-toed running socks developed by OLENO.

1.What are the benefits of five-toed socks?

First, let's look at the benefits of five-toed socks.

① Free movement of fingers improves stability

Regular running socks tend to put pressure on the toes because they are designed to cover the foot with rounded toes, but five-toed socks allow each toe to move independently , making for a more natural feeling of grip on the ground. Trail running, in particular, involves running on uneven ground , so having independent toes allows the toes to react and capture the small changes in the convex and concave surfaces, which directly translates to a more stable feeling underfoot .

In road running, the force generated when pushing off is not dispersed and is easily transmitted, making it easier to generate smooth propulsion (the same principle as when many children run barefoot in running races at sports events).

②Improve grip inside shoes

If your feet slip inside your shoes while running, you will waste energy and cause fatigue, especially on rainy days or during long runs.

※Trivia: Why does grip weaken on rainy days?

1. When your shoes get wet from rain, the surface of your socks will absorb the water more easily, which reduces friction and makes it easier for your feet to slide around in your shoes.
2. In humid environments, evaporation slows down inside the shoe, making it easier for sweat and moisture to build up , which causes the skin to soften and reduces grip .
3. When running on rainy days, the road surface becomes slippery, so you need to be more stable under your feet. If your feet slip inside your shoes , you have to use extra force to maintain your balance , which can result in fatigue.

For example, our OLENO five-toed running socks are partially made with Nanofront fiber , and are designed to maximize grip inside the shoe. Nanofront provides high grip even in dry environments, but it really shines when it's wet. As a result, it fits better with the shoe, reducing unnecessary movements and allowing you to maintain a stable running form even on rainy days.

3. Reduce the risk of blisters and chafing

Regular running socks tend to cause toes to rub against each other, which can lead to blisters and chafing when running for long periods of time. However, with five-toe socks , each toe is separate, reducing friction between the toes and preventing foot problems.

This difference is especially evident in ultramarathons and long trails . It is because of these practical benefits that five-toe socks are so popular among long-distance runners.

2. There are also additional benefits

The above are merely the advantages of five-toed running socks compared to regular running socks, but from here on I would like to compare our five-toed running socks with regular five-toed running socks .

①High water absorption and quick drying performance, less likely to become stuffy

Sweat buildup while running not only increases discomfort in the feet, but can also cause blisters and skin problems. It is especially important to take measures against moisture inside your shoes when walking on trails in the summer or on rainy days.

Our five-toe socks use our unique spinning technology. They are made of highly absorbent and quick-drying materials that quickly absorb and release sweat and moisture. In addition, they are knitted in a way that takes breathability into consideration, so they are comfortable to wear even during long runs and have the added benefit of reducing foot problems.

2. Excellent durability and long life

Running socks are prone to wear and tear and need to be replaced frequently . However, our five-toed socks use Cordura fiber , which dramatically improves durability. They are about six times more durable than regular five-toed socks, and are resistant to friction and tearing, making them less likely to develop holes even after long-term use .

Trail running is particularly prone to damage from gravel and branches, but our highly durable five-toe socks can be used safely in such environments. This is a major advantage.

3. Conversely, are there any disadvantages?

1. Difficult to put on and take off (takes time)

Because the shoes have a structure where you put your fingers through them one by one, they can be a hassle to put on, especially if you are not used to it or are in a hurry. Therefore, choosing a model with highly elastic material at the fingertips or a three-dimensionally designed finger shape will make them a little easier to put on.

2. It is difficult to choose the right size (if it doesn't fit, it can feel uncomfortable)

Just as there are 10 people with different foot shapes, the length and shape of toes are different for each person, so the fit of five-toed socks varies more from person to person than with regular socks. If you can try them on, try them on to check , or if that is difficult, choose socks with a delicate size design, such as those made in Japan .

3. Some people may feel a sense of pressure or discomfort between their fingers.

No matter how many benefits there are, there are still some people for whom five-toed socks just don't fit. In particular, people who are wearing five-toed socks for the first time or who are not used to having something between their toes may feel uncomfortable or stuffy due to the unique fit. It's a good idea to start by getting used to thin socks made of breathable material .

4. Recommended for these runners

• For those looking for stability under their feet → Ideal for trail running and speed training on the road.

• For those who suffer from blisters or chafing , you will be more likely to avoid foot problems even on long runs.

• For those who want to prevent their feet from slipping inside their shoes → High grip specifications improve the balance between shoes, feet and socks. Improves ease of running.

• If you are looking for durable running socks → They last a long time, so they are great value for money.

• For those who run on rainy days or in environments where they tend to sweat easily → Quick-drying performance prevents feet from getting sweaty.

5. Why not try our five-toe running socks?

As a company that continues to research running socks, we have developed these five-toe running socks , a highly functional model that combines all of the benefits we have introduced so far.

✅ Made of Cordura for excellent durability → Provides high durability even in particularly intense sports such as trail running.

✅Improved grip with Nanofront fibers → The extremely fine Nanofront fibers inside the shoes catch on the shoes, minimizing slipping.
✅Highly absorbent and quick-drying for a comfortable fit → Prevents foot problems (peeling skin, blisters) caused by sweaty feet, even in bad weather or when running in the middle of summer.

These are shoes that we would recommend to anyone who wants to improve the stability of their feet, run for long periods in comfort, or solve foot problems.

Currently, the official online store is running a free shipping campaign (for purchases over 5,500 yen) .

Please try our five-toe socks, which are chosen by Olympic athletes and Japanese trail running representatives.
