Our journey began in 2015 with a mission: to create high-performance running gear that fits real bodies. What started as a breakthrough in Brazil has grown into South America’s gold standard—now empowering runners worldwide.

Our Contour Fit was designed with purpose—born from the insight of real athletes who know the difference great gear makes. After countless miles of testing, we optimized every detail for support, comfort, and performance. Try Authen risk-free—we’re confident you’ll feel the difference.

Just as Bossa Nova blended Jazz and Samba, Authen combines Brazilian insight with American innovation to create performance gear that moves with every body.

Our mission isn’t just about finish lines—it’s about the countless moments that lead there. From early alarms to late-night miles, we design performance gear for runners dedicated to their own progress, no matter the pace.

We don’t wait for challenges—we seek them. Every obstacle, every failure is an opportunity to improve. Like training, authenticity is a process of constant evolution. At Authen, we embrace that journey: breaking limits, rebuilding stronger, and running toward the best version of ourselves.

AUTO + HENTES

While the modern definition of authenticity typically means genuine or reliable, we must return to the etymology of the word to truly understand Authen’s ethos. Derived from Greek root words meaning self and doer, Authentikos is defined as acting on one's own authority. We believe Authenticity is a continual journey of self-improvement, recognizing that one is always evolving rather than remaining static.

We draw deep inspiration from our nation's breathtaking beauty—the majestic Sugarloaf, the rhythmic ocean waves, the captivating mountain ranges. Nature's fluid curves and forms surround us, whether in motion or stillness. Just as the contours of our surroundings remain dynamic, the Authen "A" is no static emblem. It flexes, curves, and adjusts—a perpetual contour, in constant evolution. We believe Authen athletes maintain this same disposition: always moving, always evolving.
