The Nike women’s Flex Run 2021 ‘Iris Whisper’ delivers a pastel colorway of a sustainable running shoe made with at least 20% recycled content by weight. A soft lavender hue floods the stretchy textile upper, accented with an embroidered Swoosh and reinforced with no-sew overlays. Lightweight cushioning is provided by a foam sole unit with an extra-plush Solarsoft core. Rendered in yellow, the foam compound is visible in between a series of deep grooves cut into the outsole, which promote flexibility and the natural motion of the foot.
