A brick is an item that fails to sell—sitting on shelves or websites without generating the expected demand. The term implies the product is as desirable as an actual brick: heavy, unwanted, and going nowhere. Calling something a brick is a harsh judgment in a culture that prizes scarcity and sellouts. Items become bricks for various reasons: unappealing colorways, oversaturation, poor design choices, or simply misreading what the market wants. Even major brands release bricks—not every Supreme drop sells out, and highly anticipated releases sometimes underwhelm. Bricks often end up at outlets, discounted online, or sitting in resellers' inventory at a loss. The term also applies to resale purchases that don't appreciate: buying a shoe expecting profit only to see prices drop makes it a brick in your collection. Understanding what bricks versus what sells is considered market literacy in streetwear communities.
