Nike has made its Air Force 1 Flyknit even more environmentally friendly by adding renewable Crater Foam to its midsole, creating the Air Force 1 Crater Flyknit. Debuting in a “Wolf Grey” colorway, the Air Force 1 Crater Flyknit is built from at least 20% recycled content by weight — and blends multiple patterns and tones for a highly detailed look.Made mostly of stretchy Flyknit, the sock-like upper provides two different shades. A signature “Wolf Gray” is sued on the toeboxes and quarters, while a tri-color blend of interwoven gray, blue and red threads adds vibrance to mudguards and heels alike. Swooshes and heel tabs are done up in an off-white tone and made from a linen-like material. More pops of vibrance are provided by the bright red Nike Sportswear tongue badge and the volt green insole with a classic Nike Sunburst logo.Down below, Crater Foam midsoles are presented in “Wolf Grey” as well and feature a bumpy texture thanks to multicolor flecks of recycled rubber. Outsoles are cored out under the midfoot to save weight, but are reinforced with a classic star traction pattern on toes and heels alike to increase durability. The Nike Air Force 1 Crater Flyknit “Wolf Grey” is set to release via the Nike GB webstore on May 6. Its retail price has yet to be announced.For more from the world of the Swoosh, check out HYPEBEAST’s rankings of Travis Scott’s best Nike and Jordan Brand collaborations.
