The adidas Adizero Boston 12 is designed for runners who want to get the most out of their training and competitions and who want to cover many kilometers at a high pace. The Adizero Boston is ideal for competitions up to the half marathon distance and for interval and tempo training. Take your performance to the next level with this competition shoe! This product is part of adidas' Primegreen label. Primegreen consists of a range of high-performance materials, made from recycled components to deliver a more sustainable product. Midsole With Lightstrike 2.0 and Lightstrike Pro foam in the midsole, the shoe offers increased energy return. Adizero Boston can be used for tempo training and competitions due to the combination of foam materials. Lightstrike Pro foam ensures high energy return, while Lightstrike 2.0 foam ensures stability and good ground contact with every step you take. The adidas Adizero Boston has EnergyRods 2.0, carbon tubes that mirror the metatarsal bones and follow the anatomy of the forefoot. The Energy Rods reduce energy loss during push-off. This makes the energy return high and ensures an explosive push-off to the forefoot. Upper The Engineered Mesh upper provides support in strategic places around the midfoot and has high breathability in the forefoot. In the upper, adidas also uses 50% recycled materials to reduce the impact on the environment. Outsole Premium Continental Rubber is used in the forefoot for extra grip, even in wet conditions. An added benefit is that Continental Rubber is also very durable and abrasion-resistant. Designed with maximum grip, optimal cushioning and lightweight technology, the adidas Adizero Boston 12 helps you get closer to the finish line with every step.
