Cosmic SLR Triathlon Shoe

What Our Gearhead® Experts Are Saying:

"This is a great option for athletes who want a dedicated tri shoe that’s both stiff and easy to use in transition. The strap system is intuitive and fast, and the sole feels plenty rigid for hard race efforts without feeling harsh."

Designed specifically for the demands of triathlon racing, the Cosmic SLR Triathlon shoe from Mavic focuses on efficiency, speed, and simplicity. It’s built for athletes who need reliable power transfer on the bike and smooth, frustration-free transitions when seconds count. The shoe’s carbon composite sole provides a stiff, responsive platform that converts effort directly into forward motion, supporting sustained race intensity. Paired with a high-end Matryx upper, the structure balances lateral stability with lightweight comfort, helping maintain foot support without unnecessary bulk. This combination ensures efficient pedaling while keeping overall weight to a minimum.

A fine-tuned strap system wraps the foot securely with a single motion, reducing adjustment time during transitions. A dedicated notch in the strap holds it open and ready for fast entry after the swim, streamlining T1 without compromising fit once secured. Built with premium materials and a race-focused design, the Cosmic SLR Triathlon shoe is best suited for athletes prioritizing quick transitions, efficient power delivery, and confident performance throughout the bike leg of a triathlon.
