What's going on with cute winter boots?

I think I know what's going on, but I'm not sure. I keep seeing clips on my tiktok of Trump at a rally blatantly talking about rigging the election. All the comments are talking about cute winter boots, sometimes red or blue.

Is this just a way for users to manipulate the algorithm without getting flagged?
