Novablast 6 vs Deviate Pure Nitro 1

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.

The Deviate Pure Nitro is Puma's plateless super trainer, and it sits in a clever spot: most of the bounce of a race shoe, without the plate telling your legs what to do. It runs on a full PEBA Nitrofoam midsole with a 38mm heel and 30mm forefoot, an 8mm drop, and a listed 220g, so it is light for how much shoe you get underfoot. This is a fast everyday trainer rather than a marathon racer. It shines on tempo runs, progression runs and honest daily miles where you want a lively, energetic ride but still want your foot to do the steering. Because there is no carbon plate, it feels more natural and forgiving than a plated super trainer like the Puma Deviate Nitro Elite 4, which makes it easier to run slow in. If you want one bouncy running shoe that covers most of your week, this is a strong pick.
