Runproof refers to fabrics, particularly hosiery, that resist developing runs or ladders. Think of those leggings that don't get a massive line when you snag them. Unlike easily damaged fabrics, runproof materials have a special knit or construction. This construction prevents a small tear from unraveling into a larger run. The goal is to maintain the fabric's integrity and appearance. This is a common feature in tights and stockings. It's like a safety net for your clothes.
