Experience Flow 2 vs Novablast 6

The Experience Flow 2 is Altra's answer to runners who love the brand's roomy, natural feel but want a bit more snap. It is a lightweight daily training shoe that trades Altra's signature zero drop for a low 4mm, which nudges you onto your forefoot and helps the ride feel quick. At 238g it is genuinely light for a cushioned trainer, so it handles easy miles and picks up the pace for a tempo or progression run without feeling like a chore. Think of it as a do-most-things road shoe rather than a specialist. It is not a max-cushion recovery slab and it is not a carbon racer, but for daily running, faster sessions and the odd 10k it hits a sweet spot. If you have been curious about Altra's foot-shaped fit but found true zero drop a step too far, this is the easiest way in. In our view it is one of the more versatile shoes in the range.

The big change for version 6 is a small pod of FF Turbo Squared foam under the forefoot, set into an FF Blast Max midsole. It gives the Novablast a quicker toe-off, and most reviewers think it's the better shoe for it. Ben Parkes rates it the best Novablast so far. Fordy Runs likes the changes too, but wonders whether the series has swapped the fun of the early versions for something dependable and a little safe. One reviewer liked it much less, finding the heel dull and the transition slappy.

This is a daily training shoe for easy miles and long runs, and it can still pick up the pace for strides or a steady tempo. Both UK reviewers share one worry: the Novablast 5 lost its bounce over time for plenty of runners, and most of this midsole is the same foam. At £140 RRP it costs £5 more than the version it replaces, and the older shoe is worth a look while stock lasts.
