TuneLug™ Outsole 
Stay in control on climbs, descents, and everything in between. Co-engineered with Vibram®, the TuneLug™ outsole combines Megagrip™ for outstanding grip on wet and dry surfaces and Litebase™ for reduced weight. The conical lug geometry is custom-designed for directional control, while the 360° wrap provides added sidewall traction and durability.

Euforia™ Super Foam
A smooth ride that holds up across changing terrain. Euforia™ is Satisfy’s proprietary midsole foam, blending PEBA and EVA to deliver soft, stable cushioning for long-distance efforts without sacrificing stability. Tuned for a smooth, consistent ride across road and trail, it’s designed to feel good no matter where the run takes you.

Rippy™ 66 Monomesh
The Rippy™ 66 Monomesh Upper is constructed from Nova® Nylon 66, chosen for its strength, breathability, and resilience. This high-tenacity material stabilizes your foot, managing moisture and ensuring a secure, comfortable fit, so you stay locked in as you take on the trail.

Size guide:
TheROCKER runs true to size for performance. Expect a snug, secure fit. The upper is non-stretch, which helps lock the foot in place. If you have wider feet, prefer a more relaxed fit or more space in the toebox, going up half a size may offer more comfort.
