I had a situation where a very cute and friendly female observed me looking at her feet a few times shortly after she started working in the office. I believe she intended to have fun with me about it as she brought up one time while she was at the beach, someone asked if they could take a photo of her feet because he thought they were beautiful. She motioned towards her feet as she was speaking and I looked at her feet again even though her shoes were on. She made other obvious comments and often caught me looking, but never directly questioned me or made any comments. She did smile at me once when I stared at her feet because she was wearing flip flops and I looked as she changed into office appropriate shoes.
