About
The Techknit RNR-1 Trainer is TYR's knit-upper cross-trainer — built for athletes who want responsive cushioning and breathable comfort in a versatile gym shoe. Powered by SurgeNRG+ supercritical foam , the RNR-1 delivers responsive cushioning, shock absorption, and energy return through every training session. The breathable 3D knit upper wraps the foot in a lightweight, adaptive construction that moves with you through every rep, set, and stride. The flexible sole allows natural foot movement across training surfaces.
