Socks and dyes, what OEKO-TEX looks at

Short answer: OEKO-TEX Standard 100 is a testing system that checks textiles for harmful substances, including certain dyes. The label applies to the individual item and says nothing about durability or origin, so always check the description of the item itself.

What OEKO-TEX Standard 100 is

OEKO-TEX Standard 100 is an independent testing system in which textiles are tested for substances that may be harmful. The test covers all parts of the item, from yarn to thread and trims. The label therefore tells you something about what was measured, but nothing about where the sock was made or how long it lasts.

What the test looks at in socks

The system looks at substances such as certain dyes, heavy metals and chemicals that can remain after production. For socks this is relevant because they lie close to the skin all day. We do not promise that a particular sock carries the label, so always look at the item itself.

The label applies to the item, not the brand behind it

When you compare socks for men, you may come across OEKO-TEX Standard 100 in the description. The label applies to the specific item or its materials, and not automatically to every item from a brand. It is therefore wise to check the product page and not to conclude from one item to a whole collection.

The product classes at a glance

The label divides items into classes according to how close they come to the skin. Class II covers clothing with direct skin contact, such as socks, while stricter limits apply to items for the youngest users. The classes say something about the limit values used, and they cannot be compared with quality marks for other things.

What the label does not tell you

The label says nothing about wear resistance, fit, colour fastness over many washes or where the sock was sewn. It also says nothing about how the fibres were grown or made. If you want to know more about those things, you have to look for other information in the description or ask the retailer directly.

How to check whether an item has the label

Look at the label or the product page, where the mark and a number normally appear. The number can be looked up at the independent institute behind the system to see which item was tested. If there is nothing, do not assume that the item has the label, and ask the seller before you buy.

Colours and the first wash

Whatever the labels, it is a good habit to wash new socks before wearing them the first time. Dark colours can release a little dye in the first washes, so wash them with dark clothes. Follow the care label and do not use too much heat, so the colour and the fibres last longer.

Combining with other basics

When you have looked at the socks, you can look at the rest of the day's layers, for example bamboo clothing for men and long sleeve models as the innermost layer. Check the description here too for what is stated, and do not let one label alone decide.

In short, how to read the label

OEKO-TEX Standard 100 tells you something about tested substances in the specific item. It says nothing about durability, fit or origin. Check the item's own page, look up the number if you want to be sure, and use the label as one piece of information among several when you choose socks.

Frequently asked questions

Does the label mean the socks last longer?

No, it concerns tested substances in the item. Durability depends on the knit, the material and the care.

Does the label apply to all socks from a brand?

Not automatically. The label applies to the specific item or its materials, so check the description of the item.

Should I wash socks before wearing them?

It is a good habit. Wash new socks by the care label, and wash dark pairs with dark clothes if they release colour.
