The new Adizero Boston 13 – the pinnacle training shoe in the Adizero franchise – is updated with 13.8% more Lightstrike Pro midsole foam compared to its predecessor, resulting in a softer and more comfortable underfoot feeling. Alongside its signature re-engineered Energy Rods, the revamped mesh upper delivers lightness breathability and targeted support. New to Boston models, the LIGHTTRAXION outsole – first seen in Adios Pro 4 – is designed to reduce weight without sacrificing grip.
