The Nike Air Max 97 has had anniversaries before, but given that its 20th birthday ties in with a revival of late-'90s style, it’s a slightly bigger deal. This is one of those shoes that’s both loved and hated — an object that’s very much of its time, but one with an undeniable identity. Last year was about the Air Max 95, but next year belongs to the 97. From its inception to the strange forms it took throughout the years, Nike designer Christian Tresser’s creation has had an interesting couple of decades so far. An updated rendition of the epic running shoe. The Nike Air Max 97 was inspired by Japan’s high-speed Bullet Trains and brings back a running icon with a plush, lightweight upgrade. It modernizes its retro design with a knit upper, welded overlays and a Max Air unit for all-day comfort.
