All water shoes are ok!
Water shoes anything works for those. Flip flops.
Buy some water shoes they're not very expensive
I saw people in water shoes and in flip flops. My husband was asked to remove his flip flops for a ride once or twice all day. He just held them in his hands while going down. I recommend wearing something because the ground got hot and it was slightly sandy. It was uncomfortable to walk to different areas without any footwear.
