Underlayers & support: comfort where it really counts

What you wear under your outfit determines how freely you move. These essentials ensure less chafing, better support, and faster recovery—so you can keep running longer and more relaxed.

Sports bras (unrestricted support)

Unsure about support? Choose a high-impact sports bra that provides firm support without restricting your breathing. Wide straps, soft materials, and a good fit prevent chafing and ensure everything stays in place—even on technical trails.

Underwear (prevent chafing and irritation)

No distractions halfway through your run. Opt for seamless or flat constructions and quick-drying fabrics that won't chafe. Good sports underwear stays in place, even when climbing and descending.

Compression socks (less fatigue, more comfort)

Long runs put a lot of strain on your lower legs. Compression socks stimulate blood circulation and help reduce fatigue. Extra cushioning and support around the foot provide more comfort on rough terrain.

Compression tubes (targeted support)

Want flexibility? Compression tubes (calf sleeves) provide targeted pressure on your calves without having to change your favorite socks. Ideal for recovery, long distances, and extra support during intense runs.


Frequently Asked Questions

Is compression really necessary?
Not mandatory, but many runners experience less fatigue and faster recovery—especially on longer distances.

What is the difference between compression socks and tubes?
Socks combine compression with foot comfort; tubes focus only on the calf and can be combined with your own socks.

Can I wear this on short runs too?
Certainly—precisely because it increases comfort, you notice the difference immediately, even on shorter distances.


Smart combination

  • Combine with trail running clothing (shorts/tights) for a complete, comfortable setup
  • Choose technical socks or compression depending on distance and intensity

You don't feel good base layers—and that is exactly the point. Choose the right support and run freer, more comfortably, and with more confidence.
