why do rubber soled shoes squeak?

In: Chemistry

I’m confused which squeak? There’s an every step squeak – most likely caused by moisture, and then there’s the squeak that happens when your shoes are catching grip like in basketball. The latter is a phenomenon called stick-slip. Shoes are made to produce this sound on purpose as an auditory cue to verify that the user is getting the right amount of grip on the court. The right amount of grip being, your shoes sticks when you want it to,but has a little bit of give and slips a bit after sticking to prevent jarring the body from stopping so instantly. So the noise is the slip and the compression of the sole.
