简介：在耐克,技术的提高是焦点,耐克从未停止过追求更好。耐克的设计师们全身心投入,超越了一个又一个新的高度,力求满足运动员的需求。秉承这一理念,AirForce1二十五周年庆典只有一个目标,那就是探索AirForce1运动员和消费者的需要,根据他们的意见改进产品,以此向这个品牌创新的过去致敬。

简介：1982年,伟大的迈克尔·乔丹和摩西·马龙分别在NCAA和NBA的战场上纵横驰骋、称王称霸;同样是在1982年,伟大的设计师BruceKilgore推出了第一双AirForce1篮球鞋,并进而在篮球鞋这个战场上独占鳌头。如今,25年过去了,在这长达1/4个世纪的时间里,AirForce1非但没有被岁月所淘汰,反而愈发显示出其映照世界的光芒。AirForce1是第一款运用了气垫技术的篮球鞋,大大提高了球鞋的舒适性能、缓冲性能和支撑性能,这对篮球鞋来说堪称一场革命。
