• Thanks to the Boa^® Fit System, the TWISTER can be put on in a flash and taken off just as quickly. The lacing system can also be adjusted at any time and allows uniform lacing of the boot.
• The comfort padding and the 4 flex zones ensure optimum wear comfort - also when crawling, kneeling and driving.
• At just 2.7 kg (per pair, size 42), the TWISTER is also an absolute lightweight.
• Materials like the Sympatex^®membrane and the hydrophobic waterproof leather make the TWISTER largely waterproof.
• The multi-layer sole design with airbags between them ensures excellent cold and heat insulation.
• The ankle protection as well as steel inserts and the steel toe caps protect the foot against injuries.
• Reflective elements in the visible area offer maximum visibility, even in combination with overpants.

Optimum fit

A ruptureproof steel cable and a push-rotary knob enable rapid putting on and taking off and ensures optimum fit in seconds. The lacing system is easy to use and extremely robust.

Easily adjustable any time

The boot can be easily adjusted to the foot shape at any time. A small turn of the coiler is all it takes.

Tough and robust like stainless steel

A coated, stainless and ruptureproof, stainless steel cable is guided over the guide rails through the whole leg of the boot. The cord is optimally protected by coating. Boots with the Boa^® Fit System are extremely easy to clean, as debris cannot easily stick to it.

It's that easy!

1. Fasten Boa^® Dial
2. Push the leather tongue forward and put it on
3. Press the Boa^® Dial
4. Turn the Boa^® Dialwith the edge of your hand until the boot fits perfectly

  Hidden behind the black plastic is a coated, stainless, rupture-proof stainless steel cord. This robust cord serves for the uniform lacing of the boot. The cord is optimally protected by coating. Boots with the Boa^® Fit System are extremely easy to clean, as debris cannot easily stick to it.
