Gone for a swim?

I really hope not! Took a run over to North Queensferry and nearly got blown away down by the pier as so windy. I was very intrigued by these white high heeled shoes lying on the pier.
How did they get there? Where is the owner? I really hope she didn't go for a swim as the sea is only for fishes and mermaids today. (do mermaids need heels?!)
