Ben Kirschner’s Nike SF-AF1 might be one of Nike Sportswear’s best new offerings in years. The good news is that the Special Field movement isn’t slowing down anytime soon because we’re getting a first look at the Nike SF-AF1 Mid, scheduled to release sometime this Summer. The Nike SF-AF1 Mid features zippers on the heel for easy slip-on and a boot-like collar that was seen on the SF-AF1 original. These may be an early sample as no Swoosh or strap is seen, or this stripped down version may just be what Kirschner imagined. Stay tuned for more updates on the Nike SF-AF1 Mid and let us know what your first thoughts are.
