This latest collab between END. and Saucony looks to the human anatomy for inspiration. This rework of the Azura 2000 dubbed “The Brain” comes with panelled uppers, retro aesthetic and GRID technology all which remain the same, though comes with brain-inspired details throughout. The underlays, tongues — including the co-branded tab — and laces come in hues of brain-like pink, and there’s a bespoke pattern worked into the outsole, interior and shoebox, too. A miniature, END.-branded stress ball — modelled after a brain, of course — completes things.
