I replaced my mouse feet with 3D-printed ones
It's much easier than you might think, and costs far less than buying aftermarket alternatives

I have been using my Logitech MX Master 2S for years. It is a solid mouse that still performs well, but over time, the original skates on the bottom had worn thin and started peeling. That made it harder to glide smoothly on my desk and mouse pad. Buying a new mouse felt wasteful, and original replacement skates are neither cheap nor easy to find.
