The Nike LunarCharge Essential 'Speckle' draws inspiration from iconic Nike Sportswear models like the Air Max 90, Air Presto, Air Flow, and Air Current. It combines elements from these classics to create a sleek and seamless upper design that provides a comfortable sock-like fit. The neoprene construction of the shoe allows for a flexible forefoot environment, while the mesh application on the toe ensures breathability for enhanced comfort.
