Materials scientist Adel Djellouli and his colleagues at Harvard University conducted experiments to understand the source of the squeaking sound that occurs when basketball players slide on the court. By sliding a sneaker against a smooth glass plate and recording the process with high-speed cameras, the researchers were able to analyze the physics behind the familiar squeak.

Why it matters

The study provides insights into the complex interactions between rubber and smooth surfaces that produce the distinctive squeak heard during basketball games. Understanding these physical mechanisms can lead to improvements in shoe design and court surfaces to enhance player performance and experience.

The details

Djellouli and his team observed that the squeaking sound is generated by the rapid and repeated stick-slip motion of the shoe's rubber sole against the court surface. As the shoe slides, the rubber sticks to the surface, building up tension until it suddenly releases, causing the shoe to slip forward and vibrate, producing the characteristic squeak.

What they’re saying

“This squeaking sound when players are sliding on the floor is omnipresent.”

— Adel Djellouli

What’s next

The researchers plan to further investigate how different court surfaces and shoe materials affect the stick-slip dynamics and squeak generation, with the goal of informing the design of basketball shoes and courts to optimize player performance and experience.

The takeaway

The ubiquitous squeak of basketball shoes on the court is the result of complex physical interactions between the rubber sole and the smooth court surface. Understanding these mechanisms can lead to improvements in shoe and court design to enhance the game for players and fans alike.
