Nike has freshened up its Air Max 90 with two contrasting colorways: “Shimmer” and “Grey Fog” in light and dark polka dot patterns.The former version features a pale cream-colored palette dressed with vibrant polka dots. At the top of the shoe is an embroidered “Nike” logo placed over two circles, while the heel boasts a semi-translucent rubber “Nike” tab. At the sidewalls is a white leather Swoosh, popping out from the shoe’s suede and canvas panels and a light peach-toned midsole rounds off the details. The “Grey Fog” counterpart offers the same patterns and materials in a light monochromatic arrangement. There’s a bit more contrast between the rubber panels and the shoe’s beige gum outsole adds a subtle touch of color to the overall design.No official release dates have been confirmed, but Nike’s “Shimmer” and “Grey Fog” are expected to land soon on Nike’s website for $140 USD.If you like classic Nike silhouettes, check out the label’s homage to the Air Force 1 with a “University Red” colorway.Click here to view full gallery at HYPEBEAST
