Performance:

Cushioning:
- Cushioning indicates how well a midsole absorbs shock. More cushioning reduces stress on joints and muscles and increases comfort. Less cushioning allows for more direct contact with the ground, and therefore faster and more accurate reactions.

Grip:
- Shoes with good grip do not slip, even in wet conditions. They offer grip, adhesion and traction on different surfaces. The grip is influenced by the rubber blend, sole structure and tread depth - on firm trails a low profile tread is suitable, on mixed or challenging terrain you are best advised to go for a deep sole tread.

Protection:
- To protect your feet from rough rocks, roots or boulders, our shoes are equipped with special protective elements on the toes, heel or sides. In demanding terrain with boulders or on long hikes with heavy loads, more protection is advisable.

Flexibility vs. stiffness:
- Different types of terrain and activities require less or more flexibility from your shoe. A flexible shoe is perfect for easy terrain, supports your natural rolling motion and adapts to uneven surfaces. A stiffer shoe provides your feet and ankles with more surefootedness and precision in challenging terrain and is compatible with crampons.

Stability:
- Stability is needed first and foremost to keep your ankles from twisting. The more difficult and steeper the terrain, the more important it becomes. When touring with heavy loads, good protection is an advantage.

Lightweight:
- We design every shoe with performance in mind. That´s why weight, in combination with functionality, always plays a major role. The lighter the shoe, the more agile and faster you can move. The more durable the shoe, the more protection and stability it offers.
