The R.A.D® SYNTH - a road running shoe - is a lightweight, versatile Daily Trainer designed to disappear on foot and get out of the athlete’s way.

Its supercritical SwellFoam™ (TPEE + 40% Bio EVA) midsole balances responsiveness and cushioning with the durability to handle the daily miles of training. The outsole’s herringbone design – the highest performing traction pattern on the planet – is made from our signature sticky, textured rubber for optimal traction. An engineered mesh upper is lightweight and durable, with strategically placed venting for enhanced airflow.

Built for rhythm, it moves with you, delivering a smooth ride across the pace spectrum. The shoe that turns everyday training into flow.
