Get the most out of your fast running sessions with the unparalleled support of the adidas Adizero Boston 13. Midsole The midsole with Lightstrike and Lightstrike Pro cushioning offers lightweight cushioning with increased energy return. The combination of these foam materials allows you to use the Adizero Boston 13 during tempo training and competitions. The Lightstrike Pro foam provides high energy return while Lightstrike ensures stability and a lot of 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 dry and cool while walking. The mesh is partly made of recycled material. 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.
