Heat above 30°C is a serious challenge for any athlete or traveler. At temperatures like these, protecting your feet from excess moisture and chafing really matters. In our search for a solution, we turned for inspiration to the best engineer in the world – nature itself.

To understand how socks from the ExtraCotton® Collection work, let's revisit a few basic rules of physics and biology – the ones we built this technology on.

A natural landscape – the source of engineering ideas behind trekking socks

How it works in nature

Water travels naturally from the roots to the crown of even the tallest tree, thanks to two phenomena.

A tree with moisture travelling up its trunk from the roots

Capillary action

The trunk is made up of tiny fibers, and once water enters them, it starts moving upward – much the way liquid rises through a thin straw.

Evaporation

Leaves release moisture into the air through their surfaces. As the water evaporates, it creates tension that pulls moisture up from below and keeps it flowing continuously through the entire tree.

So what does this have to do with socks?

In trekking socks from the ExtraCotton® Collection, the same principle is at work. A special yarn is made of fibers that help carry moisture from the bottom upward. The moisture then moves into the zone above the shoe, where it evaporates into the air more easily.

That is exactly why these models help maintain comfort even in warm weather, when your feet sweat heavily as you move.

The golden rule of dry feet

For the moisture-transfer system to work at full capacity, sock height deserves attention too. If the cuff is completely hidden inside your sneaker or boot, moisture has nowhere to evaporate and simply stays trapped inside.

That is why we recommend choosing socks that sit higher than the top of your footwear – moisture escapes more easily, and your feet feel more comfortable as you move.

So what is the takeaway? Nature gave us the hint, and PROTECTOR® turned it into a technology that works for your comfort on the hottest days.
