The Complete Guide to Foot Odor Prevention: Eliminating Every Cause
Hello.
I am Akuru, the operator of the sock workshop Toré.
I have worked in the field of major apparel OEM production,
where I have manufactured millions of pairs of socks.
In this note, based on that experience,
I explain the mechanics of socks, which are usually not given much thought, as clearly as possible.
Today, I am talking about that one issue
that is absolutely unavoidable when thinking about socks.
The moment you take off your shoes
Have you ever been shocked by the smell of your own feet?
Even if you change your socks or your shoes, for some reason, they still smell.
Actually, foot odor has
a clear cause.
Moreover, most of these can be eliminated one by one.
Today, from the perspective of a sock manufacturer,
I will list all the causes of foot odor
and organize the countermeasures for each one!
The true nature of the odor
First, as a premise, let's organize the structure of the odor.
The true nature of foot odor
is not the sweat itself.
Sweat is actually almost odorless.
The problem is the resident bacteria.
Odor is created when the resident bacteria living on your feet break down sweat, dead skin cells, and sebum.
In other words, the structure of foot odor is as follows.
Sweat × Bacteria × Food (Dead skin cells/Sebum) × Humidity
When these four things come together, odor is born.
Conversely, if you reduce even one of these, you can suppress the odor.
By the way, it is said that human feet
sweat about a cup's worth in a single day.
In the enclosed environment inside a shoe,
this much sweat is produced.
It is only natural, structurally speaking,
that odor is easily created.

Culprit 1: The feet themselves
The first thing you should suspect is your feet themselves.
Cause
The feet are the part of the human body with the highest density of sweat glands.
And the spaces between the toes are areas where humidity becomes extremely high.
It is the perfect environment for bacteria.
Furthermore, something often overlooked is dirt under the nails.
Dead skin, sebum, and bacteria easily accumulate inside the nails.
If left unattended, this becomes a breeding ground for odor.
Countermeasures
Wash carefully, even between the toes
Keep nails short and clean
Regularly care for dead skin on the heels and the base of the toes
When washing your feet, instead of just "applying soap vaguely,"
simply being conscious of the spaces between your toes and around your nails will make a difference.

Culprit 2: Socks
I have made millions of pairs of socks to date.
Based on that experience,
a significant portion of the cause of foot odor lies in the socks.
The reason is simple.
Socks are the place that catches sweat first.
The design and condition of these
greatly influence the environment of the feet.
Cause
First is the issue of material.
100% cotton socks have high moisture absorption and feel good on the skin.
However, they are difficult to dry.
They are a material that has strong sweat-absorbing power,
but weak power to release it outward.
When they remain in a damp state,
bacteria easily multiply.
Next is the issue of processing.
There are broadly two types of antibacterial and deodorant processing for socks.
Spray processing → This is a method of applying treatment to the surface of the fibers.
It is effective, but
it wears off with repeated washing.
Fiber-embedded processing → This is a method of mixing antibacterial materials into the fibers themselves.
The effect lasts even after washing.
However, even if the package says "antibacterial and deodorant,"
it rarely states which processing method is used...
In inexpensive socks,
spray-on processing is often used.
And the problem with old socks.
As fibers are used over time, bacteria become embedded inside them.
No matter how much you wash them,
the bacteria deep inside the fibers cannot be removed.
Socks that won't lose their odor
might be a sign that it's time to replace them.
Countermeasures
Review your materials (wool and quick-drying materials dry easily and are less prone to bacterial growth)
Choose socks while being aware of the type of antibacterial processing
Replace old socks regularly
Turn them inside out and wash them thoroughly
Choose a size that fits your feet
Do not wear the same pair of socks consecutively

Culprit #3: Shoes
If the odor doesn't disappear even after changing your socks,
the culprit might be your shoes.
Cause
Leather shoes and boots have low breathability.
Humidity inside the shoes rises,
making it easier for bacteria to multiply.
However, even sneakers, which should be breathable,
can also become smelly.
This is because bacteria have become established in the shoes themselves.
Once bacteria settle into the insoles or the inner fabric of the shoes,
the odor will return even if you change your socks.
Once shoes get damp,
it can take more than 24 hours for them to dry completely.
If you keep wearing the same shoes every day,
you will end up wearing them again before they dry.
This is a cause of odor.
Countermeasures
Rotate between two or more pairs of shoes
Dry them thoroughly after taking them off
Replace or wash insoles regularly
Treat the inside of shoes with disinfectant spray
Wash sneakers regularly

Culprit #4: Lifestyle Habits
Finally, there are your daily habits.
They are small things, but they make a big difference when they add up.
Putting on socks without drying your feet after a bath
If you put on socks while your feet are still damp,
the humidity inside the socks rises immediately.
After a bath, dry your feet thoroughly, including between your toes, before putting on socks.
Wearing shoes for long periods
If you wear them for a long time,
any pair of socks will get stuffy.
On days you wear them for a long time, be mindful of the material you choose.
Wool or quick-drying materials are suitable.
Not taking care of calluses
Calluses on your heels and the base of your toes become food for bacteria.
Just by taking care of them regularly, you can reduce the causes of odor.
The true cause of foot odor
The cause of foot odor is not just the "feet" themselves.
Feet, socks, shoes
It is a problem of the small environment created by these three things.
And right in the middle of that is your socks.
Absorbing sweat, regulating humidity, and suppressing bacterial growth.
Socks are a small device between your feet and your shoes.
When this device functions properly,
the environment around your feet changes surprisingly.
Odor-free feet are
not created by feet alone,
nor by shoes alone.
I believe it only happens when the three elements of feet, socks, and shoes are functioning properly.
It is something that is born for the first time.
As a side note,
athlete's foot also occurs when a fungus called Trichophyton proliferates.
Athlete's foot itself is not the source of the odor,
but rather what I have been writing about all day is the cause of the odor.
In other words, it also helps prevent athlete's foot,
so it is also good for your health.
Thank you for reading until the end.
I have summarized it roughly this time.
This topic is quite deep,
so I plan to delve into it further in the future.
At the sock workshop Toré, we value this kind of design under the theme of "socks that are not flashy but can be worn every day."
