The Kjerag 01 is NNormal’s flagship trail running shoe—an ultra-responsive, featherlight design created in collaboration with elite athletes and rigorously tested across some of the most demanding terrain on Earth. Whether you're navigating loose alpine scree, hammering through muddy singletrack, or flying across technical descents, Kjerag delivers optimal propulsion, grip, and control without compromise.

This is a shoe for serious trail runners who demand not only elite-level performance but also thoughtful design choices that reduce environmental impact. Every component—from the high-resistance upper to the streamlined outsole—is purposefully selected to elevate your experience in motion while treading lightly on the planet.

Traction That Locks In. Speed That Breaks Free.

• Vibram® Megagrip Compound: Delivers industry-leading traction on both wet and dry surfaces—ideal for mixed terrain including slick rock, mud, roots, and snow.

• Vibram® Litebase Construction: Shaves 30% of sole weight by reducing base thickness, without altering lug geometry or grip. The result: faster foot turnover and less fatigue on long efforts.

Precision Upper Built for Brutal Trails

• Matryx® Jacquard Upper: Advanced woven upper constructed from individually coated polyamide threads reinforced with Kevlar®. Offers extraordinary durability, abrasion resistance, and ventilation.

• Water-Efficient Manufacturing: Produced in Ardèche, France, this upper uses 50–95% less water than traditional dyeing methods—without sacrificing color integrity or structural integrity.

• Minimalist Structure: No overlays, no excess. Every millimeter is optimized for lightweight function and long-distance durability.

Direct-Foot Contact Midsole for Better Performance

• EExpure Midsole: A new-generation foam designed specifically for trail running. Unlike traditional shoes, Kjerag’s EExpure sits directly beneath your foot—no sockliner—resulting in:

  • Superior ground feel and proprioception

  • Reduced internal slippage

  • Better energy return

  • Fewer blisters during extended efforts

  • Lightweight responsiveness on varied terrain

Sustainability without Sacrifice

• Recycled Content: Built with environmentally responsible materials that don’t cut corners on performance.

• Longevity Focused: Designed to endure hundreds of kilometers of aggressive use—reducing the need for frequent replacement and lowering total lifecycle waste.
