The Feiyi AIR3.0 shoe design skillfully draws on the elements of an airplane wing, bringing a unique visual impact and symbolism. The side of the shoe not only vividly reproduces the pattern of an airplane wing, but also implies the desire for speed, soaring and breakthrough. The smooth lines extending upwards seem to be the trajectory of the wing as it rushes up into the sky, symbolizing the runner's lightness and swiftness when running. Drawing on the wing design of an airplane wing, the upper is designed to be streamlined to reduce air resistance and improve the breathability of the running shoes. Drawing on the concept of wingspan and wing area of an airplane wing, the sole is designed to have a large area in contact with the ground to provide more stable support and reduce the risk of injury.
