At first glance, it might appear as though the Nike SFB Gen 2 GORE-TEX Black would be difficult to walk around in, let alone run around in while traveling over rough terrain. But it's lighter than it looks and can provide you with the flexibility you won't always find in other tactical boots. This boot was constructed almost entirely out of a combination of synthetic leather and nylon canvas, making it lightweight and durable. The boot includes Nike Free technology in the sole for enhanced flexibility and a traction pattern on the bottom to maintain grip on various surfaces. A standout feature is the rock shield on the interior, preventing punctures and showcasing the boot's toughness. The Nike SFB Gen 2 GORE-TEX Black was released on April 1, 2018, with an initial retail price of $195.
