What makes some sneakers squeak?

I believe it’s the softness of the rubber or vinyl that comprises the sole.
The softer the rubber, the better the contact with the floor.
I will admit to taking a child’s joy in squeaky sneakers when it rains. I don’t squeak them obsessively or obnoxiously, but I love the little yips and yelps I get when changing direction.

If I had new shoes that squeaked, and it annoyed me, I would take a walk in the dust, then wipe my feet on a dry carpet.
I can see how one squeaky sneaker could be annoying.

Usually the slippage of the rubber soles on the ground surface.

@kritper Yeah but some do and others don’t – so why?

I’ve also noticed that they can squeak from the inside. It’s happened to me before and I can’t stand it. If my heels slip at all in new shoes, the squeaks happen because of the slippage between my heel and the shoe. From the outside, I assume it has something to do with weight distribution.

Only one of your new sneakers squeak, @janbb?
As in the sneaker squeaks, internally?

I always called them “squeakers”!

According to Charles Shultz, creator of the “Peanuts” comic strip, the squeak from shoes occurs when the bill of sale for said shoes isn’t completely paid off.
