R.A.D - SYNTH

Every run. Every pace. One shoe.

Finding the perfect daily running shoe usually means making compromises. Too soft and you lose responsiveness. Too firm and long runs become a grind. The R.A.D® SYNTH strikes the sweet spot, delivering lightweight comfort, responsive cushioning, and exceptional durability for the kilometres that matter most.

Designed for runners who want one shoe that can handle everything from easy recovery runs to faster tempo sessions, the SYNTH disappears on foot so you can focus purely on your stride. Whether you’re training for your next race, building weekly mileage, or simply looking for a premium road running shoe in Australia, the R.A.D® SYNTH is built to keep you moving.

WHAT MAKES THE SYNTH DIFFERENT

The R.A.D® SYNTH was created with one goal: make every training run feel effortless. Rather than chasing extremes of softness or speed, it delivers a balanced ride that adapts naturally across different paces, making it the ideal everyday training partner.

At the heart of the shoe is SwellFoam™, a premium supercritical midsole combining TPEE with 40% Bio EVA. This advanced compound provides an energetic, responsive feel while maintaining the cushioning needed for longer runs and the durability required for daily mileage. The result is a ride that feels smooth, lively, and consistent whether you’re heading out for an easy recovery jog or increasing the pace for interval work.

With a 38mm heel stack and 6mm heel-to-toe drop, the SYNTH offers generous protection without sacrificing a natural running position. The geometry promotes smooth transitions from heel strike to toe-off, helping runners maintain rhythm throughout every kilometre.

Underfoot, R.A.D®’s signature sticky rubber outsole features a full herringbone traction pattern—widely regarded as one of the highest-performing grip designs available. It delivers confident traction across wet roads, footpaths, and everyday running surfaces while standing up to thousands of training kilometres.

Up top, the lightweight engineered mesh upper combines durability with strategically placed ventilation zones to maximise airflow. The breathable construction keeps feet cool while disappearing around the foot for a secure, distraction-free fit.
