With the Converse Chuck Taylor All Star Crater, Converse‘s 100-plus-year-old classic firmly evolves in the pursuit of sustainability. Its design draws from Nike’s pioneering Space Hippie efforts but does so with a unique constraint: preserve the DNA of the world’s most iconic sneaker.

Translating the Space Hippie design ethos to the silhouette required overcoming three key challenges: Applying Crater Foam to a Chuck shape, identifying a viable upper materials, and radically rethinking the use of reinforcer materials.

More than 100 people collaborated to meet these challenges.

The Converse Chuck Taylor All Star Crater is part of NIKE, Inc.’s Move to Zero journey toward zero carbon and zero waste. In turning trash into a beautiful new articulation of the Chuck Taylor All Star, Converse achieves at least 40 percent recycled content by total weight marker, making it one of Converse’s most sustainable sneakers to date. The aesthetic, in all its perfectly-imperfect glory, also forms the basis for future Converse Renew collections, which will draft off of select materials.

The Converse Chuck Taylor All Star Crater releases July 23 from converse.com.
