Adizero Boston 13 vs Mach 7

Adidas left the Boston 13's ride close to version 12 and put most of the update into comfort, with a padded heel and tongue and a new mesh upper. There's also more Lightstrike Pro sitting above the stiff carbon-infused rods. It's still a firm tempo shoe that's happiest once the pace picks up, and at £140 it's a cheaper way into rod-assisted speed than a proper carbon racing shoe. Its biggest rival is another adidas. Ben Parkes and Fordy Runs both liked the Boston 13, and both reckoned most runners would have more fun in the lighter, softer Adizero Evo SL. The Boston's argument is durability and a steadier platform, so we'd point it at runners who want one hard-wearing pair for workouts and marathon-block long runs. If you already own a Boston 12 you get on with, the changes are small.

The Hoka Mach 7 is the brand's do-it-all tempo trainer, a lightweight road shoe that wants to cover almost everything between an easy jog and a genuine session. There is no carbon plate here and that is the point. Instead you get a supercritical EVA midsole that feels lively and quick without the aggressive, one-pace demands of a racer. With a low 5mm drop and a 37mm heel stack it sits in the sweet spot for runners who want one shoe for daily miles, tempo runs and the odd longer effort. It is a clear step on from the Mach 6, keeping the versatile, pick-up-and-go character that made the line popular. At £130 it is fairly priced for a modern lightweight trainer. We rate it as one of the smartest single-shoe buys for club runners who log steady mileage but still like to push the pace once or twice a week.
