A lot of exclusives eventually find their way to PC yes… but it can take some time and sometimes ports are less than perfect. So, again, it all comes down to how much you enjoy these. If it is of no concern to you yes you can sell your PS. Also it has excellent resale value.

You are not getting the Sony exclusives anytime soon on PC. So if you like these (the next big thing would be FFXVI I guess) you may want to hold on to your PS. Other than that PC and Xbox seem redundant.

In most case if you want shoes to work with, you end up with boots. A good pair will go over your budget, and they will probably not be breathable as you mean it, but people typically wear them for hours on end and never complain. Also a good pair will probably last a lot longer than just a year unless you work in the most demanding environment, in which case a tough pair of boots was a good idea to begin with anyway.

You can look at the channel Rose Anvil on YouTube. Most vids are random boots and shoes being reviewed which won’t help much if you don’t know what you want, but there are a few rankings as well which could give you ideas. https://youtube.com/@RoseAnvil

I came for the "instruction unclear" comment but this will do.
