Millennium Marine Sidekick Issue

I love the seats, but one small issue and looking to make a permanent solution. I have a Lowe Roughneck Aluminum boat. The feet on the legs are starching the paint. Has anyone installed covers on these or something besides placing cardboard under them? My wife mentioned tennis balls, but I was think maybe soft sided Velcro or something along those lines. Anyone else do something for this? Thanks

I use carpet cut to size and glue to feet. Works good

Felt pads for furniture on hardwood floors would work. Wal-Mart sells them already round. Sticky on one side and felt on the other. Just the first thing that came to mind.

I bought this, cut it to size and attached on a similar seat mount:
