Nike Air VaporMax 2020 Flyknit GS Iron Grey.

Kid’s Shoes.

The Nike Air VaporMax 2020 Flyknit offers more than innovative wearability. The design represents our next step toward a more sustainable future. By incorporating waste-saving methods and materials—like Nike Grind in the outsole and recycled polyester yarns in the upper—each and every pair is made of at least 50% recycled content by weight.

Product Details.

The first 1-piece Air unit to run the entire length of a shoe, it allows for smoother transitions and adds unbelievable cushioning.
Stretchy and supportive Flyknit upper is made from post-industrial recycled yarn and creates a striking visual that's seamless, breathable and feels as light as air.
Made from at least 40% recycled materials, it lets you look good by doing good.
Collar sculpts the ankle for a sporty look that feels great while padding on the heel adds to the comfort.
Recycled rubber on the sole adds durability and traction, putting a finishing touch on the shoe that lets you walk the talk.

All sales are final on all launch products (not limited to Retro Jordans, Quickstrikes, Yeezys, etc.), swimwear/underwear products, discount, promotion, and sale items.
