Just like in garment construction, fit is key. Presser feet are no different.
Usually when people talk about presser feet, they're talking about the whole slew of feet types that accomplish different specialty functions like zipper feet, or buttonhole feet. However, regardless of function, each presser foot attaches to your machine at the shank via a thumbscrew or a separate mounting mechanism. Over the years, shank shape and height have evolved depending on the manufacturer. More importantly, each machine only works with presser feet made for its specific shank type.
