The Nike Air Max 270 ‘Go the Extra Smile’ spotlights the lifestyle runner’s eponymous cushioning technology with a bright yellow finish. Nestled under the heel, the large-volume Max Air unit works in tandem with a cushy white Phylon midsole. The upper is crafted from airy black mesh with tonal no-sew overlays and inner-sleeve construction for a snug, supportive fit. ‘Go the extra smile’ is inscribed on the custom sockliner and a yellow webbing pull tab affixed to the heel.
