Our Verdict

ASICS NOVABLAST 5

ASICS MEGABLAST

The ASICS NOVABLAST 5 and ASICS MEGABLAST can both get you blasted in different ways. The NOVABLAST 5 is a modern daily trainer that feels lightweight, cushioned, and pleasantly bouncy, but it keeps things in balance so it works best as a reliable companion for everyday miles and moderate efforts. The MEGABLAST takes that formula to the extreme, with a taller stack of FF Turbo² foam that makes it lighter, more cushioned, and far more energetic underfoot. It truly feels like a "mega" version of the NOVABLAST, delivering the ultimate bouncy experience with greater versatility for long runs, daily miles, and even uptempo work. If you want a dependable trainer for shorter daily runs, the NOVABLAST is a safe choice, but if you are looking for maximum bounce with the ability to shift gears, the MEGABLAST is the more exciting option.
