Learn moreThe Boston Marathon is a race. But it's also a goal, and a training plan and all the days it stays on your mind before the big one. The Adizero Boston 12 Shoes are built for mid- to long-distance running. They bring a race-day feel to training with a propulsive feel that comes from the glass-fibre infused ENERGYRODS 2.0, which limit energy loss underfoot. They're fast, but that does not come at the cost of durability — the midsole layers ultra-light LIGHTSTRIKE PRO cushioning with a new version of durable LIGHTSTRIKE 2.0 EVA.
Take on your tempo training runs with a breathable fit. Experience targeted support from engineered key zones, providing both midfoot lockdown and forefoot flexibility.
A holistic structure system designed for a seamless transition from heel to toe, bringing race-day performance to high-speed training runs.
A layered midsole construction made of our high-performance foam Lightstrike Pro plus the all-new Lightstrike 2.0, engineered to deliver a cushioned and dynamic ride. The Continental™ outsole provides superior grip in the most demanding conditions.
