If your ex's toes are facing your toes and body, this is a sign of affection.  Your ex may be still interested in you, or at least willing to be friendly and open to talking.  This is a good sign. Restless legs such as shaking, or foot tapping, are generally related to nervousness, impatience, or readiness to move on to something else.  Foot tapping shows that your ex is ready to get going, not matter if you two spoke for a brief or long time.  They may be nervous about seeing you again, or feel uncomfortable.  If your ex's feet appear uneasy, your ex is likely uneasy.  Don't force your ex into a conversation, but if there is a way to relieve anxiety and awkwardness by talking about something you both enjoy, feel free to try.  See if he or she calms down; otherwise, possibly talk another time. Conversely, if your ex appears to want touch you feet with their feet, this is a strong sign of attraction, and they are eager to be with you.  Think clearly about if this is what you want too. If their feet and knees immediately turn away from you, this may mean they don't want to talk with you, even if their face doesn't give anything away.  Feet can be more honest than a facial expression about whether you're talking with someone who dislikes you. If their feet are planted strong and solid, they may be showing, or trying to show, confidence.
