Nike Sportswear pays homage to Bill Bowerman, the man who ignited the greatest sports outfitting movement in the world, with the Air Trainer 1 ‘BB51’; these two Air Trainer 1 colorways are of the Premium NRG grade as they feature top-notch leather and suede materials with a woven tongue and gold underlays on the Swoosh. Additional details seen on both high-class renditions of the Air Trainer 1 are bold, diagonal striping on the outrigger of the fore-foot strap, the ‘BB51’ lettering on the heel, leather/suede fore-foot straps, and solid black rubber outsoles. The ‘BB51’ lettering on the heel signifies Bowerman’s initials as well as his football jersey uniform from when he played football for the University of Oregon nearly one century ago.
