Neutral & Racing | Medium Cushion | 7mm Heel Drop

The Boston Marathon is a race. But it's also a goal, 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-fiber-infused ENERGYRODS 2.0, which limits 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.

• Lace closure
• Lightweight mesh upper

• ENERGYRODS limit energy loss

• Midsole drop: 7 mm (heel: 38 mm / forefoot: 31 mm)
