Released in 1998, the Air Max Plus introduced Nike's Tuned Air system. , and as such became retrospectively known as the Air Max TN, Air Max Tuned, or Air Max Tuned 1 (TN1). Designed by Sean McDowell, the Air Max Plus featured transverse waves inspired by palm trees, and a prominent arch shank inspired by a whale tail. The initial release featured a "Hyper Blue" colorway, characterized by a fading blue airbrush effect. The Nike swoosh had a slightly irregular appearance as a border was added along the inner edge, as opposed to the outer surface. Although the shoe only had modest success in North America, in Europe they were massively popular - particularly in France, where the Plus grew to enjoy iconic status among youth culture in Paris and Marseille, where the shoe has the nickname Le Requin ("The Shark") - often anglicised into "Rekin". Part of the shoe's appeal is both its exclusivity (for many years it was only available from Foot Locker stores) and its high price. In some areas of LGBT sub-culture in France and many other European nations (most notably Germany and the United Kingdom) the Plus/TN is one of the most coveted Air Max models among foot, sneaker and sportswear fetishists.
