23. Nike Air Rift
Loved and despised in equal quantities, the Air Rift brought some tradition, common sense and glorious weirdness to the running shoe. Feeling like the ancestor of some early split-toe Onitsuka efforts (themselves steeped in age-old Japanese tradition), these were a solution for the Kenyan athletes who favored running in bare feet. Nike would unleash some other fine experiments in minimalism (the excellent Mayfly's one-marathon concept being one) but this became a trend-level favorite, with stores like the London stores shifting them at a markup with a waiting list too, after buying up batches from running retailers. Kenyan colors, Brazil colors, Turbo Pink, tangerine and camo all got wear from both sexes. And we'll probably see a Rift resurgence too.
