First introduced in 1991 as part of the Nike international series, the big window has been a longstanding favorite for performance running. For its 25th anniversary, the classic celebrated with an iteration of the Nike Air Max BW Ultra. Having been released in a barrage of colors, the sneaker is now available in a monochromatic combination of black, pure platinum and white. The black Hyperfuse upper is supported by a platinum toecap and mudguard with matching Swoosh, resting atop a white midsole with a black Ultra outsole. The Nike WMNS Air Max BW Ultra is now available at retailers such as Titolo.
