What Our Gearhead(R) Experts Are Saying:"I use the Boston 13 for weekly threshold workouts and long runs. The extra Lightstrike Pro foam keeps things soft yet springy, and the EnergyRods give it just the right structure to feel stable without being stiff. They're fast, breathable, and reliable even on longer runs."We train smarter and race stronger with the adidas Adizero Boston 13 Shoes. Designed for tempo sessions, long progression runs, and peak marathon prep, this shoe delivers speed and support with every stride. A light mesh upper offers breathability and lockdown, while the updated platform brings even more energy return than its predecessor. With 13. 8% more Lightstrike Pro in the midsole and re-engineered ENERGYRODS 2. 0, we get cushioned propulsion from footstrike through toe-off. The Continental(TM) Rubber and LIGHTTRAXION outsole grips across conditions, making this one of our go-to trainers whether we're logging weekday mileage or chasing race-day goals.
