A peculiar yet pervasive problem in households worldwide—smelly shoes—has inspired two Indian researchers to delve into the science behind the stench. Vikash Kumar, an assistant professor of design at Shiv Nadar University, and his former student Sarthak Mittal, embarked on a journey to understand how foul-smelling footwear affects the experience of using a shoe rack. Their innovative research not only addressed a common annoyance but also earned them the Ig Nobel Prize, a prestigious award celebrating unusual and imaginative scientific endeavors. The duo’s study began with a simple observation: students often left their shoes outside their rooms due to the overpowering odor, not due to a lack of space. A survey of 149 university students revealed that more than half had felt embarrassed by their own or someone else’s smelly shoes. Traditional remedies like tea bags or baking soda proved ineffective. Turning to science, the researchers identified Kytococcus sedentarius, a bacterium thriving in sweaty shoes, as the primary culprit. Their experiments demonstrated that a brief exposure to UVC light effectively killed the bacteria and eliminated the odor. However, timing was crucial—too much exposure damaged the shoes. Their solution? A prototype shoe rack equipped with UVC tube lights, designed to store and sterilize shoes simultaneously. The Ig Nobel Prize recognized their work, highlighting the fun and imaginative side of science. The award has not only brought recognition but also inspired the researchers to explore more unconventional scientific questions. As Kumar aptly put it, today’s smelly sneakers could pave the way for tomorrow’s groundbreaking discoveries.
