Nike SB Zoom Blazer Mid Iso (Dark Russet/Sail-Dark Russet) Featuring supple brown leather, a gum rubber sole and a nylon tongue, the Nike SB Zoom Blazer Mid has a vintage, familiar vibe. Orange details on the insole and tongue label finish the look off while nodding to the color of Nike&39;s original shoebox, which made its debut in 1971. Nylon tongue adds a familiar, vintage look. Orange details throughout, including on the tongue label and insole, nod to Nike DNA. Zoom Air unit feels springy and responsive. Vulcanized construction fuses the sole to the upper for a flexible, broken-in feel. Gum rubber sole is grippy and classic.
