The adizero Boston 12 shoes are designed for middle- and long-distance running. Thanks to ENERGYRODS 2.0 technology with glass-fibre elements, energy loss is kept to a minimum for race-day performance and feel even in training. They’re fast, but not at the expense of durability: the midsole combines ultralight LIGHTSTRIKE PRO cushioning with a new version of the hard-wearing LIGHTSTRIKE 2.0 EVA compound.
