These two are close. Fit will decide it, so try both on.

On the run

Superblast 3: The do-everything super trainer. Very soft and protective, with a full stack of foam that still feels light. Bouncy enough for tempo days and long runs alike, though the FF Blast+ base keeps it from being as springy as the softest top layer suggests.

Sonicblast 2: Huge cushion for high mileage. Soft and protective, with exceptional shock absorption and plenty of foam for long, easy miles. Less lively than you might expect, and not as stable as some max-stack trainers.
