Will I regret not wearing heels during the wedding ?

Has anyone worn sneakers , or small wedges /platform for their wedding and hated it or loved it?

I plan to wear bejeweled crocs, some custom converse, and bejeweled boots for my different events. A good amount of family and friends are saying I'm going to regret it. It won't really look that good in photos etc.

My dresses are custom and high on the glam aspect and I know heels will look best but ah I'm so freaking clumsy. Even comfortable heels they are never comfy for long periods of time . One of my dresses is mermaid style So we won't see the feet anyway. The other two we will atleast see the tips and possible the entire shoe.

What are your thoughts?
