Megablast 1 vs Novablast 6

The Asics Megablast is the brand's big, bouncy super trainer: a plateless max-stack running shoe that sits above the Superblast as the softer, taller, more cushioned option in the line. There is no carbon plate here, so the propulsion comes purely from a huge 46mm heel of FF Turbo Squared foam and the shape of the sole. That makes it a versatile do-everything trainer rather than a pure speed tool. It soaks up easy miles, holds a long run together, and still has enough energy return to lift into a steady tempo when you want it. At 230g it is not light for a trainer, and at £229 it is priced like a race shoe, so it asks a lot up front. But if you want one cushioned shoe that covers most of your week without a plate dictating the ride, the Megablast makes a strong case. We rate it as a premium daily-to-long-run trainer with real pop.

The Novablast 6 is Asics at its most playful: a high-stack, bouncy daily training shoe built to make easy miles fun and steady miles feel effortless. At 249g with a big 41.5mm heel it sits in the upper reaches of the daily trainer class, closer to a max-cushion cruiser than a lean workhorse, yet the FF Blast Max midsole keeps it lively rather than dull. This is the do-everything running shoe for the runner who wants one pair for most of the week: warm-ups, recovery jogs, long runs and the odd relaxed tempo. It is not a race shoe and it is not a stability shoe, so if you overpronate heavily or want firm ground feel, look elsewhere. But as a cushioned, spirited daily trainer at a sensible price, we rate it highly. The Novablast 5 fans will feel right at home, with a touch more bounce underfoot.
