  • Stay secure with every step

    High side walls and wrapping heel design enhance stability while staying flexible.

Why we developed FLEXTRON

Mountain hikes demand endurance, confidence, and balance – especially on long trails. Traditional hiking shoes can lead to fatigue, ankle strain, and reduced energy when you need it most. FLEXTRON solves these challenges.

How it works

The TPU midsole acts like a springboard, boosting rebound energy as you push off. The innovative shank delivers torsional stability, helping you stay balanced on uneven ground, while high side walls wrap the heel and midfoot for security and flexibility. By reducing strain on your calves and feet, FLEXTRON keeps you moving efficiently and helps you recover faster – so you’re ready for the next peak.
