In 1998, designer Sean McDowell created the Air Max Plus, popularly known as the "TN", inspired by sketches he had drawn while on vacation in Florida, observing the black silhouettes of palm trees against a blue-toned sunset. This gave rise to the iconic wavy lines ("waves") running along the side of the shoe, together with the innovative Tuned Air system. The Black Sapphire White colorway revisits this technical heritage with a palette combining deep black with sapphire blue and white accents, resulting in a look that is as striking as it is true to the model's original spirit.
The Air Max Plus is instantly recognizable by its TPU cage with wavy lines inspired by palm trees, its pronounced arch inspired by a whale's tail, and its Tuned Air technology, which uses two hemispheres in the sole and air unit to optimize stability and reduce pressure on the heel. In the Black Sapphire White version, those waves stand out against a black base with sapphire blue and white details, reinforcing the technical, futuristic character that made this silhouette an icon from its launch.
At Next Step, we sell only 100% new and authentic footwear, verified before every shipment. You have 14 calendar days to return them if you need to exchange them. We offer fast shipping throughout Spain and Europe so you receive them without delay.
Their black base with sapphire blue accents makes them ideal for urban looks in dark tones: pair them with black joggers, gray cargo pants, or dark jeans for a cohesive streetwear style. For a more striking contrast, wear them with a white or light gray outfit that makes the blue details stand out. Perfect for anyone looking for a TN with a personality of its own without sacrificing everyday versatility.
