Livestrong x Nike Sportswear Air Max 90
The Air Max 90 had a 20% larger Air bag than the AM 1 so the window got larger and the shoe wider, characteristics that added weight. Hatfield compensated by designing an upper that used lighter materials. New mold techniques and eyelet technologies gave runners more options than they had ever experienced in a shoe before. The addition of more plastic components, along with geometric blocking that shuffled colors from midsole to the upper, gave the shoe a faster look and called out the bigger Air bag. Hatfield also separated the midsole into front and back compartments to allow a range of performance and material options.
