Iconic cycling socks designed in Belgium, crafted in Italy

Johan, Greg, Tom, Marianne, Remco… We’re not all pros, but that doesn’t mean we can’t look like one.

You don’t have to be a professional cyclist to look like one. ISOCK was born from exactly that idea — that every rider, amateur or seasoned club racer, deserves to roll out with the kind of style you usually only see on the pro peloton. These Belgian-designed cycling socks prove that the right pair of socks is the easiest upgrade you can make to any kit.

Brand Intro

ISOCK was founded by Eric De Clercq, who describes himself as more of a domestique than a team leader — but very much the driving force behind the brand. Based in Belgium, ISOCK designs cycling socks that combine technical performance with distinctive, bold graphics inspired by the legends of the sport. The socks are produced in northern Italy, by a small family workshop on the shores of Lake Garda that has specialised in sock manufacturing for three generations.

Inspiring Story

On the shores of Lake Garda, two brothers run the factory that their father and grandfather built — not by automating, but by perfecting. Every ISOCK design is woven on machines adjusted to the finest detail by craftsmen who know their trade inside out. Before any design goes into production, it is first approved on the machine itself — an extra quality check that guarantees what you receive is exactly what was designed. It is this long-standing partnership, rooted in shared values of craftsmanship and sustainable quality, that gives ISOCK its edge.

Who is this for?

You ride every weekend, maybe a sportive or two a year. You’re not racing for prize money, but you take your kit seriously. You want cycling socks that stay fresh after dozens of washes, don’t lose their shape, and turn a few heads at the café stop. You also appreciate it when a brand stands for something beyond the product — whether that’s a beautifully told story or support for a cause that matters.

KOTK Socks: Cycling for a Cause

A note on the name — it’s a Flemish thing

KOTK is the abbreviation of Kom op tegen Kanker, which in Dutch means “Stand Up to Cancer.” The name is exclusively Flemish — spoken in the Dutch-speaking north of Belgium. It is not a French-language organisation and does not operate under the same name in Wallonia (French-speaking Belgium) or Brussels.

In Wallonia, the equivalent cancer charity is La Fondation contre le Cancer (also known as Stichting tegen Kanker in Dutch), which is a separate, federally funded organisation active across all of Belgium. The two organisations exist side by side, each serving their own linguistic community. So if you’re an international reader puzzled by the abbreviation: KOTK = Kom op tegen Kanker = a proudly Flemish NGO fighting cancer.

ISOCK partnered with Kom op tegen Kanker to create an exclusive range of charity cycling socks. With every pair purchased, €10 goes directly to cancer research and patient support. The KOTK range comes in several colourways — including KOTK Sole and KOTK White — so you can ride in style while making a real contribution.

For a small Belgian brand, this is a meaningful commitment: €10 per pair is substantial relative to the product price, and it connects the cycling community directly to one of Flanders’ most recognised charities.
