most wooden clogs come with rubber soles nowadays to make them bearable to wear for more than an hour
Or, we should stop paving road surfaces so wooden clogs work again as intended without being painful after a while.

Paving is a solution to a much worse problem of huge maintenance costs of non paved roads and paths. Unimproved dirt doesn't stand up well and gravel needs more maintenance than paving as well.
Now I am imagining a mars rover that works like one of these. Stampeding over the rocky landscape, powered by martian wind.
Given that Mars’ atmosphere density is only about one percent of Earth’s, that seems unlikely.
I remember seeing an exhibition of these many years ago that included demos [1]. It was outstanding (evidenced by the fact that I still remember). I wonder if he still does tours and exhibitions. If so, be sure to check them out. [1] https://www.chicago.gov/city/en/depts/dca/supp_info/strandbe...
For anyone who wants to know more: This is an application of Jansen's linkage: https://en.wikipedia.org/wiki/Jansen%27s_linkage There are other similar linkages but Jansen's is quite good. For anyone who doesn't have an idea why something like this matters or is inspiring beyond art, legged vehicles have many downsides but one big upside is that you can theoretically avoid the rubber/microplastic particulate emission…
Are any companies doing r&d for drop in tire replacements that don't have as much of an issue with micro plastics?

It says these are made of plastic pipe. Doesn't the pipe wear down where it contacts (or even slides in the video) the ground, creating microplastics? Also, it already slides some of the time in the videos. Not sure what the advantage is over a simple slide dragged by a sail.

Before there was asphalt/tarmac/blacktop there was "macadam", which was tarmacadam without the tar. But it used to kick up huge amounts of dust, so it was normal to pour water on the roads in hot weather.

That's wrong: the problem is the rubber on the wheel (or feet in case of legs) being spent due to the traction and emission of rubber microparticles as it is.
Yes sorry I wasn't clear enough. Rubber and chemicals from tires on the nice road surfaces. That's what that should have said. But the legs are still a solution in search of a problem.

Flying cars would solve this problem.
