The Nike Air Max Tn aka AMP was released in the fall of 1998. The shoe was the first running shoe to feature Nike’s Tuned Air system. The line was to use the blow-moulded air system, combining low air pressure with mechanical elements. A balance of impact protection and motion control. Hemisphere placement for localised control and stability. Guides the foot throughout footstrike. Tuned for different-sized feet. The Air Max TN was a huge hit in London,USA and Europe (especially France).
