R.A.D® Unisex Synth Running Shoes - Off White

The R.A.D® Unisex Synth Running Shoes – Off White are lightweight, versatile road-running shoes designed to handle everything from relaxed daily miles to faster training sessions. Built to feel almost invisible on foot, the Synth combines responsive SwellFoam™ cushioning, a breathable engineered mesh upper, and high-grip rubber traction for a smooth ride across a wide range of paces.

The clean Off White colorway gives this performance-focused daily trainer a versatile, understated look. At just 232 g (US Men's 9), the Synth keeps weight low while delivering the cushioning and durability needed to consistently handle daily training.

Supercritical SwellFoam™ for Daily Miles

The Synth features a supercritical SwellFoam™ midsole made from 40% bio-based EVA and TPEE. This lightweight foam balances responsive energy return with comfortable cushioning, creating a versatile platform for easy runs, steady efforts, and up-tempo sessions.

A 38 mm heel stack and 6 mm drop provide ample underfoot protection while maintaining a smooth, agile feel. The geometry is designed to work naturally across different running speeds, making the Synth an adaptable option when you want one shoe for much of your weekly road training.

Lightweight Grip & Breathability

Underfoot, a herringbone-pattern rubber outsole uses R.A.D's sticky, textured rubber compound to provide dependable traction on road surfaces. The pattern is designed to maintain grip without compromising the shoe's lightweight, fluid ride.

Up top, the engineered mesh upper balances lightweight durability with strategically positioned ventilation for increased airflow during demanding runs.
