The women’s Nike Air Max Tailwind 4 LX ‘Hydrogen Grey’ features a metallic silver finish on the retro runner’s signature TPU ‘fingers,’ allowing them to stand out against the gradient tan and light blue coloring of the textile upper. The same hues are applied in mismatched fashion to the side leather overlays on each shoe. It all rides on a white foam midsole, fitted with visible Max Air units for lightweight cushioning.
