Our Verdict
HOKA Mach 7
R.A.D SYNTH
The HOKA Mach 7 and R.A.D SYNTH are both lightweight trainers with daily mileage and uptempo range, but they don't deliver that versatility the same way. The HOKA is lighter, bouncier, and more energetic underfoot, which makes it better suited to pickups, steady efforts, and runs where you want the shoe to turn over quickly. The R.A.D feels a bit more cushioned as the distance piles up, giving it a touch more underfoot protection for longer daily runs, but it doesn't have the same lively snap when you start pushing the pace.
