Legends are created, never made. Only time can tell their story. Celebrate five years of breakthrough Boost performance in these men's shoes. Part of the Boost anniversary pack, the shoes feature an adidas Primeknit upper that adapts and adjusts to the changing shape of your foot as you run. Targeted support in the midfoot and heel provide a locked-down fit, while Boost delivers an energized push-off. A grippy outsole grabs surfaces with superior traction for a stable stride.
