The Air Force 1 GS 'Recycled Wool Pack - White' is a grade-school shoe. Featuring a sustainable construction, the shoe's synthetic leather upper is built with at least 25% recycled fibers, while 20% recycled poleyster makes up the laces. The tongue and heel patch emerge in felt that is 100% recycled, and underfoot, the rubber sole unit is partially composed of Nike Grind rubber, as noted by the speckled design throughout. Never worn
