Specifically designed to meet the needs of Bo Jackson's versatile athletic regime, the Nike Air Trainer Max '91 is back in all of its glory. Released in 1991, this all-purpose cross-trainer was constructed to perform whether you were lifting weights, running laps, or engaged in pounding cardio exercise. The popularity of Bo Jackson and his two-sport heroics, along with a unique look and "never before seen" zig-zag support strap, made the Air Trainer Max '91 an instant hit. Plus, they were also backed by Nike's long running "Bo Knows" ad campaign. Thankfully, Nike re-released the Air Trainer Max '91 in the original Grey Stone/ Yellow colorway. But, the classic is also available in Black/ White and Black/ Varsity Red. Pick up one of the greatest cross-trainers ever made, you won't be disappointed.
