The Kjerag 02 is the go-to choice when your training demands speed on rough terrain. It’s built for the sessions that sharpen your edge—tempo climbs, hard intervals, and steep push-to-the-limit efforts—where every foot strike, breath, and mindset aligns to push you further. This isn’t just a race-day shoe; it’s a bootcamp for your fast-twitch tempo, ready to turn effort into measurable gains on every trail.

Rooted in the original Kjerag DNA, the 02 model re-engineers key elements for quicker rebound, enhanced comfort, and lasting durability. The outsole remains a proven workhorse, while the upper, midsole, and materials have been refined to deliver more propulsion, better feel, and fewer hot spots mile after mile. It’s no longer Kilian’s shoe alone—it’s yours to own, whatever your fast looks like—time, terrain, or a snappier stride.
