About this product
The Courtflash silhouette comes in lucid ray blue, footwear white and dark blue, a three-colour combination with clear contrast. This unisex adidas design combines imitation leather and textile across the upper, with a textile lining and synthetic sole. The hook-and-loop closure gives it a distinctive fastening detail. It includes removable, contoured and padded insoles, as well as adidas Cloudfoam. The lightweight construction completes the feature set, while the mix of materials and shades gives the shoe a varied appearance.
