R.A.D ® SYNTH

The R.A.D ® SYNTH is the ultimate lightweight daily trainer that practically disappears on your feet — designed to stay completely out of your way so you can focus purely on your run.

At its heart is our innovative SwellFoam™ midsole, a supercritical blend of TPEE and 40% bio-based EVA. It strikes the perfect balance between responsive energy return and plush cushioning, while offering the durability needed to handle high weekly mileage without breaking down.

The outsole features a herringbone pattern — widely regarded as the highest-performing traction design in the world — crafted from our signature sticky, textured rubber compound for confident grip in all conditions. Up top, a lightweight engineered mesh upper delivers excellent breathability through strategic venting zones, while maintaining the structure and durability you need for everyday training.

Built for rhythm and flow, the Synth moves naturally with you, offering a smooth, versatile ride whether you’re doing easy miles, steady efforts, or up-tempo sessions. It’s the shoe that transforms your daily training into something that just feels right.
