Good, better, test winner!

How do socks become test winners?

Since the production of the first sock in 1999, our socks have been systematically and regularly tested for fabric and thread. Thanks to this quality control, our socks have become test winners.

Due to their high cotton content, our Calf socks Classic have been a popular test object since the beginning. Not only we test our socks regularly, but also Kassensturz and K-Tipp. Find out more about our test winner and the test results of recent years.

The test winner: the classic calf sock

Our bestseller is made from 81% Pima cotton and therefore hardly fluffs. With their ribbed surface, the calf socks also provide extra support and comfort.

Originally only available in black, the sock test winner is now also available in various bright colors.

Multiple in the sock test


Several times the BLACKSOCKS Calf socks Classic selected to be subjected to the test criteria of independent tests. Various methods are used to test the socks and their durability to their limits.

Our bestsellers prevailed against thirteen socks in the men's socks test conducted by the TV consumer magazine "Kassensturz" in 2008. With a top score of 5.2 out of a possible 6 points, our efforts for quality are confirmed not only by our customers, but also by the test results.


The calf socks also achieved a solid performance in the K-Tipp sock test in 2012. The test reports from 2003 and 2008, our own checks and over 3 million socks sold to satisfied customers enable us to provide a consistent assessment from a third party perspective.

Unique quality

To turn a ball of cotton into the ideal sock, several intermediate steps are necessary, all of which contribute to the quality of the product.

Our socks come from a factory in Portugal. Before the socks are finished, we carry out various wear and laboratory tests.

Skin-friendly socks

It is important to us that our textiles are 100% skin-friendly. That's why our socks, underpants and T-shirts comply with the Oeko-Tex Standard 100.
