The Nike Blazer Mid '77 PURPLE takes advantage of the classic Nike Basketball look with a vintage finish on the midsole, making it look like you've had them in storage for years. Leather and synthetic upper for comfortable support. The vintage design of the midsole gives them a classic style. Autoclave construction that fuses the outsole with the midsole to offer a stylized look. Exposed foam on the tongue for a retro look. Smooth, non-marking rubber outsole with herringbone pattern for excellent traction and durability.
