Unconventional styling and innovative technology made the adidas Crazy BYW X an icon in the 90s. Issued in March 2019, this Core Black update carries a split-patterned mesh upper with a ribbed Primeknit collar, dynamic lace closure and wavy, asymmetrical side panels. Inverted branding in gold is stamped on the front-facing pull tab. Responsive Boost pods and a semi-transparent rubber outsole are based on the Feet You Wear concept.
