The Nike SF Air Force 1 Mid GS 'Ocean Bliss' shoe updates the military-inspired design in kids’ sizing in an allover light blue hue with tonal details and a sleek gum midsole. The 'Special Field' edition of the Air Force 1 designed by Ben Kirschner originally debuted in late 2016, with weather-resistant materials like ballistic nylon, military straps and utilitarian detailing. The SF-AF1 Mid released shortly after, boasting an adjustable ankle strap, back zips and an encapsulated Air-Sole unit.
