Asics Novablast 6 vs Topo Athletic Phantom 4

The Novablast 6 is the livelier, bouncier trainer with a rockered foam midsole and a roomy wide fit; the Phantom 4 is the more grounded, lower-drop option with a broad toe box. Both are neutral daily trainers. The Novablast runs heavier and its knit upper draws mixed durability comments, while the Phantom 4's ZipFoam 2.0 feels firmer and less springy. Pick the Novablast for tempo-friendly cushioning and the Phantom 4 for a natural, low-drop ride with toe room.

• Choose the Novablast 6 if you want a springy, rockered daily trainer with generous cushioning and a wide fit.
• Choose the Phantom 4 if you prefer a lower drop, a broad toe box and a firmer, more grounded ride.
