Ader Error, a collective based in Seoul, and Puma have collaborated to create a unique collection called 'Under Creativity'. This collection embraces imperfection and combines different subcultures with innovative design. One of the notable pieces from the line is the CGR sneaker, which was introduced in October 2019. The sneaker features a white textile and Surf the Web suede material, complemented by leather Formstrips, a hairy suede counter, and a buckle on the heel. The design also incorporates visible stitching and a hang tag, which adds to the deconstructed aesthetic. Additionally, the sneaker includes an EVA-cushioned rubber cupsole, which adds a modern touch to the classic tennis tooling.
