How far can Nike go? The Nike Air Max 90 Flywire TZ takes a hefty chunk of weight out of the heel unit and fleshes it out with feather lightness on the upper. As flexi as Nadia Comaneci, the completely seamless upper is reinforced with the pencil thin flywire technology enabling you to bend your foot to double jointed proportions. Keeping the sneaker monochromatic in grey hues, with touches of black and white, the simplicity of the shoe has actually got us fiending for a pair down at SF’s HQ. Did someone say Tron?
