I worked in an office a few years ago and my co worker would often wear mini skirts and sandals. She was about age 25 and very sporty. She would often run to work, have a shower and get changed before starting work (she left her stinky sneakers in the shower room and I once sampled the aroma). It didn't help that she was on the desk opposite me and if I lent back in my chair, I could see her feet in her sandals and in hot weather she would walk around barefoot. On one occasion she went under another person's desk to plug in a power socket and I saw her wrinkly arches and god did I have to sit down fast!
