Seems like you are very interested in a male foot mold made of latex. More interested, by your line of questioning, than saving a footprint find in plaster which saves a footprint find perfectly for study. Plaster casts are well accepted by science in all manner of footprint and fossil preservation. I can only think of a couple of uses of a male latex mold. Another word for a male latex foot mold is a latex prosthetic foot. Since I doubt that you want to help a footless bigfoot, it seems you want to create a latex prosthetic foot for some other purpose. A prosthetic foot is most commonly used for hoaxing. Either way, you are on your own at this point because I am suspicious of your intentions. And as an aside, if you show up in a month or two on the forum with footprint or track way pictures, I doubt anyone would believe them at this point. The forum rules are very harsh on hoaxers and that is a quick trip to being permanently banned.
