Nike "Just Do It" (1988)

Nike's "Just Do It" era is the most recognized athletic identity on earth — a black ground, a single white Swoosh, a hero athlete in mid-action, and Futura Bold Condensed shouting in ALL CAPS. Born in Beaverton in 1971 and galvanized by Wieden+Kennedy's 1988 campaign, it turned a shoe company into a cultural institution.

The visual language is brutal simplicity. No gradients, no ornament, no playfulness. Full-bleed photography crops carry narrative; type carries command; negative space carries intensity. When color enters, it is punched — a Volt-yellow flash, a heritage red — never decoration. The design says: move, or get out of the way.

耐克"Just Do It"是地球上最具辨识度的运动品牌形象——黑色底色、一只白色对勾、正在动作中的运动员、以及Futura Bold Condensed字体以纯大写铺满版面的口号。它从1971年俄勒冈州比弗顿的小公司起步，1988年经Wieden+Kennedy广告公司点燃，把一家卖鞋的公司变成了文化机构。

视觉语言是残酷的简洁：没有渐变、没有装饰、没有俏皮感。整屏裁切的运动员大片承担叙事，压紧字距的超粗凝缩体承担命令感，充沛的负空间承担张力。色彩永远是"一击"——要么是一抹Volt荧光黄，要么是一块传承红——从不用来装点。整个体系只说一件事：动起来，或者让路。
