Smart knitting zones

The upper features strategically placed knitted panels to provide targeted support for different areas of the foot – offering stability where needed and flexibility where the foot moves. This creates a comfortable fit that adapts dynamically to your movements.

Fine merino lining

The inner lining, made from fine merino wool, creates a soft, comfortably warm environment for your feet – ensuring comfort when worn barefoot without any odours. It provides natural moisture management within the shoe. At the same time, the material feels particularly soft against the skin.

Goodbye laces

Elastic laces replace traditional lacing: simply slip them on, enjoy a perfect fit, and start running straight away. The system saves time in your daily routine whilst ensuring a consistent, comfortable fit across the instep.

Damping concept

The insole, Phylon midsole and rubber outsole work together as a system – for maximum energy return and noticeable joint protection with every step. The lightweight Phylon midsole absorbs impact and supports a smooth, springy roll-off motion.

Non-slip sole

The rubber outsole provides a secure grip on a variety of surfaces – whether city pavements, parquet flooring or light terrain. The distinctive tread pattern ensures grip that is both visually appealing and highly effective.

Handy loops

The heel loop provides enough space to put the shoe on easily and comfortably, making it particularly easy to slip on in everyday life. The asymmetrical loop keeps the tongue securely in place and ensures an even fit across the instep.
