High heels don't necessarily make a woman's legs look better, but they can be a cultural signal that implies sexy. I think the beauty of a woman's or a man's feet can be revealed by low cut loafers or semi open sandals. There is a sense of nudity and sensuality that is far more sexy than impossible stiletto heels. Subtle design and muted colors are interesting without being distracting. The attention should go to the whole presentation, not just "OMG look at those shoes"...kind of like "WOW, look at those pink flamingoes in their lawn!"
