90° right angle socks

A person's heel is a right angle. That's why we knit the heel at 90 degrees.

General socks are made of 120°. We want to deliver the comfort that comes from a mere 30° difference to as many people as possible.

With that in mind, the development of right-angle socks began, and we have continued to research and improve them over many years. Today, all MUJI socks are right-angled.

Feature 1: Fits the heel

The right angle is the same as the shape of the foot, so the heel is completely wrapped.

Feature 2: Hard to slip off

The heel fits perfectly, so there is no excess fabric and it does not slip even when you move.

Feature 3: Not too tight

It does not slip even when you move, so you don't have to tighten your feet.

Sneaker In

Socks that are long enough to show the ankle. Developed after many trials so that they do not come off or slip when you take off your shoes or when you are walking.

Regular socks

Socks that reach mid-calf length. The opening of the shoe is at the widest part of the foot, so even if it is less tight, it is designed to prevent it from slipping off.

Short socks

These are short socks that reach above the ankle. We have added variations in colors and patterns so that it can be used as an accent for coordination.

Foot cover

A foot cover that is shallower than sneaker-in socks. Developed after many trials so that they do not come off or slip when you take off your shoes or when you are walking.

Kids' socks

We have adopted a unique heel that can accommodate a wide range of sizes so that you can wear it as you grow. The size display is woven into the inside of the leg opening so that even siblings can distinguish between them. You can also write your name.

Tips and storage that help your socks last longer

Socks have the image of being a quick consumable item, but if you make small habits, you can wear them for a long time.

MUJI product developer discussion - care and storage tips to extend longevity of socks.

A product developer who has experience in sock manufacturing delivers the beauty of socks and living tips related to socks.

Socks are a type of clothing that we wear every day, just like underwear.
If the socks that protect your feet and support "walking" slip off every time you walk, have holes, or have pilling, they are redundent.

Here are some tips on how to make your socks last longer.

Tips to make socks last longer
  • If you are unsure about which size to choose, choose the larger one. If friction is added while the socks are stretched, they will be damaged faster.
    Example: If your shoes are 23 cm, choose 23-25 ​​cm socks instead of 21-23 cm socks. 
  • Wear shoes that fit your feet. If the shoe size is too big or too snug, the friction of the sock inside the shoe
    will increase and cause holes.
  • Please pay attention to the type of shoes. If the inside is rough, the friction with the socks increases and pilling is likely to occur, making it easier for holes to form.
  • Storage space is also important. Store it in a place where it is not exposed to sunlight or fluorescent lights.
    (Avoid direct sunlight when drying.)
  • Put your valuable socks in a laundry net and wash them. Mixing fabric softener reduces the friction between fibers, making it less prone to pilling.
  • If you have a pill...While the pill is still small, use a pill remover or scissors to carefully remove the pill.
  • Keep your toenails short and tidy to prevent any abrasion to the fabric..

Relationship between odours and materials

For those who are concerned about stuffiness and odours, we recommend socks with a high blend of natural materials such as cotton.

The relationship between odours and materials

At MUJI, we value the power of natural materials such as cotton, linen, and wool when making our products.
Based on the same idea, we use materials such as cotton, silk, and wool for our socks.

Why we use natural materials

The reason is that we believe that the "natural function" of the material is excellent, not to mention the texture.
Cotton, which is most commonly used for socks, has high moisture absorption and excellent breathability, so it
absorbs sweat from your feet.

Sweat and odors to worry about in summer

The soles of the feet are said to be the part of the body where the sweat glands are concentrated and sweat the most.
If the socks themselves have poor hygroscopicity, sweat will have no place to go, and the heat inside the shoes will tend to get stuffy.

In shoes that have become hot and humid, various bacteria grow and the sources of odors increase, resulting in odors from feet, socks, and shoes.

For those who are concerned about stuffiness and smell, one solution is to choose socks with a high blend of natural materials such as cotton.

What is recommended for the mixed composition of socks

If socks with a high blend of natural materials are considered good, then 100% cotton socks are better. In fact, 100% cotton socks are rarely seen on the market.

General socks are knitted by mixing threads such as "polyester" and "polyurethane" in addition to "cotton". These materials are used as rubber, to reinforce the toe area, and are necessary for the fit of socks.
It is possible to make socks with 100% cotton, but if you use only cotton, the socks will not fit well and will slip off.

MUJI currently does not sell 100% cotton socks that have a weak fit. However, in order to allow you to feel the comfort of cotton, we have increased the amount of cotton used as much as possible.

While carefully using natural materials, we aim to create socks that fit the feet, do not slip off, and are comfortable to wear, while incorporating improvements in our designs every day.

Stay comfortable with MUJI socks in all seasons.

Correct way to wash socks

Socks that are washed casually are especially easy to get dirty and easily breed bacteria.Here's how to properly wash and dry your clothes to make them last longer.

Points for washing

  • Before washing, dust off the surface (if it is damp with sweat, etc., dry it ).
  • When washing, turn it inside out (you can leave it inside out when drying). In the case of a vertical washing machine, put it in the bottom with the highest detergency.
  • When drying, put the opening between the clothespins (pinch one place where the toes are in the loop).
  • For stubborn mud stains, soak and wash before washing.
  • For socks containing wool or silk, wash them by hand as much as possible using a neutral detergent.

Let's see why.

Why wash inside out

Reason 1:
General socks use stretchy threads on the side (inside) that touches the skin.
This thread has a crimped shape to give it stretch. As a result, protein stains such as the skin of your feet and keratin will get entangled in the thread while you are wearing it. This entangled protein stain is difficult to remove with detergent, so it can easily become a breeding ground for bacteria and cause odours. Washing inside out makes it easier to remove dirt. (It is also effective for stockings and tights.) Before washing, tap the dust on the surface to remove it as much as possible.

Reason 2:
Dark coloured socks such as black and navy will turn slightly whitish after being washed several times.
This is not because the colour has faded, but because the fibers of the sock are becoming fuzzy.
Washing the socks inside out reduces friction during washing and prevents the socks from becoming fuzzy (whitish).

Reasons for drying from the opening

Laundry tends to dry from above. Water also moves downward due to gravity.
If you dry with the toes up (the opening down), it will take a long time for the opening to dry, and the weight of the moisture will stretch the opening. In addition, the thread used to give the opening stretchability is prone to deterioration due to moisture, so it is necessary to remove moisture as soon as possible. Chlorine bleach should not be used because it will easily deteriorate the stretchy yarn.

The reason why soaking and washing is good for stubborn mud stains

Mud stains are a state in which small particles of mud, sand grains, dust, etc. are trapped deep inside the fibers.
You have to physically push the particles out of the fiber. In addition, dirt is often coated with oil such as sebum, so it is necessary to remove the oil as well. Dissolve heavy-duty laundry soap in water below 40°C and soak for 30 minutes to 2 hours. If you are particularly concerned about dirt, rinse the socks once with water, rub the soap directly on the dirt, and then soak them in soapy water. Place the soaked soapy water in the washing machine and wash.

Why use a mild detergent for wool or silk socks?

Wool and silk are made of the same protein as human skin. Alkaline detergents can easily damage the surface of the fabric, so gentle washing with low-temperature water and a neutral detergent will prolong the life of your socks.
Also, both fibers are vulnerable to friction, so it is important to wash without rubbing.

Socks, which we always wash casually, are among the items of clothing that are particularly prone to dirt and bacteria.
By properly washing and drying, you can remove the dirt that causes the smell and make it last longer.
