TL;WR: Are all dark tennis shoes really that bad for a non- business professional interview weekend with walking when I don't have a lot of shoe options? Will casual shoes ruin my chances if I'm dressed business casual?
I have an interview coming up in a week or so for chemistry. I was told we didn't need to worry about wearing suits, and that the atmosphere was casual for the weekend. That said, I plan to be more business casual than "just presentable" casual.
Unfortunately, I have a healing foot injury and cannot wear heels or flats and don't currently have nice shoes as I wear tennis shoes for lab.
Is it okay to wear sneakers if this isn't business professional and I was told casual but I want to look presentable? Will they even see my feet? Flats don't have enough support for my feet and we'll be walking a lot.
