The Nike Blazer Mid '77 Vintage takes advantage of the classic Nike Basketball look with a vintage finish on the midsole, so it looks like you've had it 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 for a streamlined look. Exposed foam on the tongue for a retro look. Smooth, non-marking rubber outsole with a herringbone pattern for excellent traction and durability.
