Product description

Conquer Technical Trails with lightweight Precision. There’s something empowering about choosing the harder path — the steeper hill, the longer route, the trail that makes your legs burn and your heart beat harder. If that’s where you find your focus, your freedom, your strength — then Fosen was built for you. Not sure which size to choose? If you're between two sizes, we recommend going one size up. Why it is your trail partner on tougher terrain: • Light, fast, and made for motion. At just 367g (EU 39), Fosen gives you the agility of a low-cut shoe with the confidence of a mountain boot. It’s perfect for those who move quickly and purposefully over uneven, technical trails. • Dry feet in wet conditions. The GORE-TEX® with ePE membrane (PFAS Compliant), keeps your feet dry, no matter the forecast. Breathable, waterproof, and built for unpredictable weather. Fosen respects both your journey and the planet. • Precision fit for better control. The extended lacing system lets you fine-tune the fit for your foot and terrain — tighter for descents, looser for open flats. It’s support adapts to how you move. • Secure and comfortable footing when the trail fights back. Built on Alfa’s NORTIK last, Fosen hugs your foot while giving it room to move naturally. The design keeps you balanced, reduces fatigue, and gives you control when every step counts. • Stronger than it looks and made to last. Crafted with a bio-circular Dyneema® fiber, this upper is lightweight but tough — resistant to abrasion, wear, and time. Built for easy repair. They're light enough to let you keep climbing, strong enough to handle rough ground, and smart enough to keep your feet dry, stable, and comfortable from base to ridge. The versatile look let’s you use this at any point of your journey, from you exit your door, to the top of a mountain. For the hikes that challenge you — and the ones that remind you why you love it. Fosen is the shoe for those who seek out elevation, push through switchbacks, and smile at the top — not because it was easy, but because it was worth it.

Yes. The Fosen APS GTX M features a GORE-TEX® ePE membrane, which provides reliable waterproofing while remaining breathable. Your feet stay dry and comfortable in rain, or variable terrain—without overheating on the move.

Who is the Fosen APS GTX M designed for?

Fosen is built for fast hikers who need lightweight footwear that performs in demanding terrain. At just 367 g (EU 39), it delivers the agility of a low-cut shoe with extra support—ideal for those who move quickly and decisively.

What makes Fosen’s construction special?

Several design details set Fosen apart:

An extended lacing system that allows precise adjustment for comfort and control.
Alfa’s NORTIK last, which provides stability while following the foot’s natural motion.
Lightweight build for reduced fatigue without compromising grip or durability.

What is Dyneema®, and why is it used in Fosen?

Dyneema® is an advanced fiber that is 15 times stronger than steel by weight, yet incredibly light. On the Fosen APS GTX M, the Dyneema®/nylon upper makes the shoe highly abrasion-resistant and durable while keeping the weight to a minimum. This ensures protection against sharp rocks, branches, and rough terrain—without adding bulk. It also contributes to the boot’s sustainability, as the material is repairable, extending the shoe’s lifespan.

What makes Fosen APS GTX M worth the investment?

Fosen combines lightweight agility, GORE-TEX® waterproofing, and Dyneema® durability into a shoe built for long-term performance. Instead of cycling through pairs of lightweight shoes that wear out quickly, you get sustainable materials, repair-friendly design, and Alfa’s nearly 100 years of Norwegian craftsmanship. It’s not just a shoe—it’s a high-performance tool built for demanding adventures.
