Increase your speed with the responsive cushioning of the adidas Adizero Boston 13, perfect for fast interval training. The shoe for when you pick up the pace! Midsole With its Lightstrike and Lightstrike Pro foam, the midsole offers lightweight cushioning with increased energy return. Adizero Boston 13 can be used for tempo training and competitions due to the combination of the foam materials. Lightstrike Pro foam ensures high energy return, while Lightstrike foam ensures stability and ground contact with every step. Upper The upper of the Adizero Boston 13 is made of lightweight mesh that wicks moisture away from your foot, keeping you cool and dry as you walk. The mesh is partly made from recycled materials. Outsole With every step you take, it is important to have good grip and for this model, a strip of premium Continental Rubber is available on the forefoot. This type of rubber offers superior grip and traction with every type of run. The rest of the outsole consists of a new type of rubber called Lighttraxion, which is lighter in weight, but can offer the same firm grip in racing conditions.
