Cosmic SLR Triathlon Shoe

What Our Gearhead® Experts Are Saying:

"I’ve used these in short- and middle-distance races where every second in transition matters. The strap stays open and easy to grab, and once it’s closed the fit feels secure without fiddling. On the bike, the sole feels stiff and responsive, which really helps when you’re trying to settle into race pace fast."

The Cosmic SLR Triathlon shoe from Mavic is built for fast, efficient racing, where smooth transitions and immediate power transfer make a real difference. From flying out of T1 to locking into race cadence, this shoe is designed to disappear beneath us while keeping speed front and center. A carbon composite sole paired with a Matryx upper delivers a stable, supportive platform that maximizes pedaling efficiency without sacrificing comfort. The engineered strap wraps the foot quickly and securely, while a dedicated notch keeps the closure open and ready for fast transitions. Lightweight materials keep the shoe responsive and comfortable through the bike leg, helping us stay focused on effort, pacing, and the run ahead.
