The adidas ZX 2K Boost 2.0 ‘White Blue Bird’ presents a subtle two-tone colorway of the retro-inspired lifestyle runner. The airy upper is constructed from off-white knit textile, fortified with tonal synthetic overlays and a translucent external heel counter. Gradient blue three-stripes adorn the quarter panel, while interchangeable Velcro patches can be affixed to the tongue tag for a custom look. The lightweight build is mounted on a full-length Boost midsole that’s partially caged for improved rearfoot stability.
