Adizero Boston 12 vs Mach 7

The Adizero Boston 12 is adidas at its most versatile: a £160 tempo running shoe built to be the one trainer that handles almost everything bar your easy days. It is the rod-equipped middle child of the Adizero family, sitting below the Adios Pro racers but with enough snap to make threshold sessions and long runs feel purposeful. At 267g with a 7mm drop it is not feather-light, and the ride leans firm and direct rather than soft and forgiving. That is the point. Push the pace and the Boston rewards you with a propulsive, slightly aggressive roll through toe-off. Jog it slowly and it can feel stiff and a touch dead underfoot. In our view this is a do-it-all daily trainer for committed runners who like a firmer, faster shoe, and a genuinely capable marathon training partner. The newer Adizero Boston 13 softens and lightens the formula if this version reads too stiff for you.

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.
