Ok. I am guessing that modified shoes would be too much work for multiple pitchers, so you probably want some kind of force sensing mats on the mound. This company seems to have a ready made system but they don’t even show prices so it’s probably way expensive.
Here’s an interesting instructible similar to your goal which should be not too expensive
You definitely roll your own system with load cells and a multipart platform, I am not sure how consistent the foot placement is for pitching. You can make each platform segment have 4 load cells (one at each corner) and calculate average force that way.
You could also use FSRs for the platform corner sensors.
You could make some shoe attachments like old school roller skates used to clip onto shoes where you add the load cells or FSRs instead of trucks/wheels.
