Anyone who does trail running, marathons, or road running will have problems at least once.

• Skin peeling due to sweaty feet
• Skin peeling due to blisters

This is actually something that many top runners suffer from , and I get the impression that many of them try various things, wondering if it's their shoes or their running style that are to blame, but are unable to improve.

Of course, if you find the perfect shoes and run in the best possible way, there will be some areas that can be improved, but aren't there also some aspects that can't be changed by shoes or running style in the first place?

This is caused by the socks that sit between your feet and your shoes, and although it may not improve if you don't change your socks, it may also be a quick fix.

So, this time we will explain the functions of socks that are necessary to prevent your feet from getting sweaty and causing blisters.

[Sweaty feet]

The main cause is poor absorbency of socks.

The reason your feet get sweaty is simple : sweat from the soles, toes, and other parts of your feet is not absorbed by the socks and remains there , causing the humidity to rise abnormally . One of the standards for measuring the performance of socks is their water absorbency , and socks with low water absorbency will end up in the condition described above.

In fact, absorbency depends on the material used in the socks. Materials such as wool and silk are highly absorbent, but polyester has low absorbency .

Socks used in active sports such as trail running, marathons, and road marathons are often made of polyester .

This is because polyester is a fiber that is very resistant to friction and can withstand vigorous movements, and is also a material that dries quickly . This makes it an ideal material for sports socks, which are washed frequently.

As mentioned above, they have low water absorption, which means that your feet tend to get sweaty.

Therefore, if you are troubled by sweaty feet, it is best to choose socks that use a lot of highly absorbent materials (such as cotton, silk, linen, etc.). However, you should be careful because there is a high possibility that the durability will decrease.

This is not a sales pitch or anything, but at OLENO we are introducing socks for trail running and marathons that are made from a special highly absorbent polyester, so if you're interested, please take a look.

"Ultimate SHR" is designed to thoroughly absorb water and dry quickly.

Poor ventilation is also a cause

Not only water absorption, but also poor breathability can lead to sweaty feet. The more loosely knit the socks are, the more breathable they can be. Conversely, if they are knitted tightly like thick socks, the breathability will be poor .

A very rough pair of socks would be ones with a mesh structure . They obviously have good breathability, but they also get caught more easily and are more likely to tear or become damaged.

If you want to use your socks for a long time, why not look for socks that are just the right amount of rough and not prone to snagging ? (You can't tell with the naked eye, so it's best to ask someone at the sock department.)

The main cause of blisters is friction between the feet and the shoes.

In fact, sweaty socks can also cause blisters. Originally, socks are also responsible for reducing friction between your feet and shoes, but if socks get sweaty, their ability to reduce friction decreases, making them more susceptible to blisters.

However, in addition to sweaty feet, another common cause is the accumulation of small misalignments between your shoes and your feet . This is not a problem if you are just going out for a normal walk or doing a light run, but if you are running for a long time, such as a trail run or marathon, the story is different.

If you find shoes that fit perfectly, without slipping even a millimeter, you probably won't get blisters. However, it's not easy to find shoes like that, so if you're worried about blisters, I recommend socks with strong anti-slip properties .

However, there are cases where anti-slip features are only used as a token gesture , or where there is a lot of anti-slip material but the grip is not that strong , so I think it's a good idea to try them on once to see if they prevent slipping.

Above, we have introduced the functions of socks to prevent feet from getting sweaty and blisters.

When running a marathon or trail running, people pay attention to their shoes, clothes, and equipment, but I think there are still not many people who pay attention to their socks. However, because it is a sport that puts a lot of strain on the feet, I strongly think that you should pay attention to your socks and run comfortably.

OLENO is a long-established sock manufacturer with over 70 years of history, and we make and sell socks with an uncompromising focus on quality. Our socks are used by top athletes in a variety of sports, and we will continue to support athletes and runners who challenge their limits by treating them not as "consumables" but as "equipment."
