Adidas Adizero Boston 12 Blue Spark

FAST-TEMPO TRAINING SHOES WITH HIGH PERFORMANCE TECHNOLOGY.

The 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.
