Should a prom dress cover your shoes?

I'm curious, should a prom dress really cover one's shoes? It's such a traditional event, but with the ever-evolving fashion trends, wouldn't showing off a pair of stylish heels or flats add a touch of modernity and flair? On the other hand, some argue that the dress should Flow seamlessly from top to bottom, creating a cohesive and elegant look. What are your thoughts on this? Is it more important to follow convention or to make a bold statement with your footwear?
