SFB Origins

The SFB collection honors Nike cofounder Bill Bowerman and his WWII service. Upon his return, he became the head track and field coach at his alma mater, the University of Oregon, where he began creating high-performance footwear for his athletes. Just like Bowerman, everything in the SFB collection is field-proven and dedicated to athletes.
