R.A.D® SYNTH is a lightweight road-running daily trainer designed to feel natural underfoot and stay out of the athlete’s way.
Its supercritical SwellFoam™ midsole, made with TPEE and 40% Bio EVA, balances responsive cushioning with the durability needed for everyday training. A smooth ride across the pace spectrum keeps each run feeling fluid.
The outsole features a herringbone traction pattern made from R.A.D’s signature sticky, textured rubber for strong traction. An engineered mesh upper keeps the shoe lightweight and durable, with strategically placed venting for enhanced airflow.
Built for rhythm, the R.A.D® SYNTH delivers a smooth, flowing ride for everyday training and a range of paces.
