The Air Zoom Structure 20 'Black Total Orange' is specifically designed for a stable, responsive ride and breathable flexibility, thanks to its Dynamic Support design and engineered Flymesh upper. Unlike previous versions, this road racing shoe has reduced Nike Flywire cables, which are now limited to the upper two laces. To ensure a customized fit, the lower laces are attached to inner straps that wrap around the foot. Additionally, the blown rubber outsole provides reliable shock absorption, making it perfect for absorbing the impact of repeated motion.
