Mach X 2 vs Deviate Pure Nitro 1

Heel rub is the first thing to know about the Mach X 2. Nearly every review mentions it: the heel collar is thin and unpadded, several testers got blisters in the first few runs, and another found it dug into the Achilles. Get past that and the ride is why people put up with it. It's a rockered, snappy super trainer that reviewers took from easy runs to track reps, and Believe in the Run graded its performance an A.

Doctors of Running were less convinced, finding it heavy for fast running and unstable for one of their testers. Hoka has since released the Mach X 3, which reviewers rate more highly, so the 2 makes most sense as a discounted buy. At £180 RRP it's hard to choose over its successor, but check the price table, because an older super trainer at a good discount is a different proposition.

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.
