Bridesmaid shoes

I am picking the color and then letting them pick the style. My bridesmaids vary significantly in height (one of my friends is 5'10", two are around 5' 7", four are around 5' 2", one is only 5ft.) so one heel height just would not work. Plus, I want them all to feel comfortable and be able to dance all night without taking their shoes off! I also want them to be able to spend what they feel is within budget.

They are required to wear a black dressy shoe for the ceremony, I don't care if it's flats or heels, they also need yo wear them for photos and for a portion of the reception (where their shoes may be in additional photos), afterward if they want to wear any shoe they want.

As long as its gold i dont care

I said black shoes- heels, flats, it doesn't matter to me. I think one is wearing heels, one flats and another might be wearing boots

I said silver and let them chose. They did send me a pic of what they wanted before they bought them just in case. Since they all had the same dress I didn't want them to be TOO matchy.

My BM's have the same knee length dresses, so I wanted them to personalize it with shoes, hair, and jewelry. I said it has to be white, gold, or beige and they can choose whatever they want, just make sure that it doesn't clash with the dress style. I wanted them to be able to be themselves while having a nice dress to connect them together.

One of my BM's are buying 2 pairs of shoes, she's only 5'1" so she wants to wear some massive heels at the ceremony, but she's getting flats for the reception since it'll be on grass.
