I’m a wrestler and really struggle with getting a secure fit. This isn’t specific to Airpods, but it does seem worse than other buds. I tried foam tips from Comply. They worked reasonably well, but their longevity was short and the small size means there isn’t much physical room for them to compress/expand for a good fit. Some attachment issues as well (though I’ve heard they had been sorted out).

More Airpod Pro form factors would be welcome, but the functionality is pretty good.

I switched to Comply foam tips and they stay in a lot better. Not perfect, but the best fit I've had with in-ear headphones ever.

The only ones that stay in better are the OG Airpods with no noise cancelling. The shape fits my ear perfectly.

Anything that goes in the ear canal? Always pops out eventually.

I find the Pros migrate out no matter what size I use. I was hopeful that the new XS size on the v2 Pros would help, but it doesn't appear to.

As a result, I use my old Airpods (not sure what gen, but pre-Pro) for zoom calls. I don't need ANC under these circumstances, and I prefer to not be reaching for my ear every couple minutes to push the pod back in.

I have small ear canals and tried every possible aftermarket ear piece for my airpods pro to no avail. Now I use bone conducting earphones. They don't sound nearly as good and they don't block outside noise (which is both a negative and a positive depending on the situation), but they work well for all kinds of activity.

I got some memory foam tips for mine and they've been amazing.

There are 3rd party tips you could try.
