Nike Alphafly 3 Blueprint Pack Bowerman First, in the early 1970s, Bill Bowerman poured rubber into a waffle iron and changed running forever. The Nike Alphafly 3 Blueprint Pack Bowerman Blueprint Pack looks back to that moment — hand-drawn blueprints as the colorway of the most advanced marathon shoe Nike has ever built. First, the origin story. Then, the technology. The Blueprint Pack connects Nike's founding obsession with speed to the platform that currently holds marathon world records.
