Adizero Boston 12 vs Hyperion 2

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 Hyperion 2 is Brooks at its most versatile: a light, non-plated speed trainer built to make your fast days feel fast without asking you to save it for race morning. At 204g it sits comfortably in lightweight-trainer territory, and the ride is snappy and low to the ground rather than soft and plush. There is no carbon plate here, which is the whole point. You get a natural, flexible foot feel that rewards a quick turnover, so it handles tempo runs, intervals and strides better than it handles slow miles. In our view this is one of the more honest running shoes in its class: it does not pretend to be a marathon super-shoe, and it is better for it. If you want a single pair for structured speed work, or a first proper 5K and 10K racer, the Hyperion 2 earns its place. The newer Hyperion 3 refines the same idea if you want the latest version.
