Never Show The Sole Of Your Shoe

If you don’t want to appear disrespectful and risk offending someone, never assume a sitting position that will result to the bottom or sole of your shoe to point at anyone. For men who like to cross their legs by placing one foot above the other knee, better consider crossing your legs like the ladies so that the bottom of your shoe will always point downwards. If this is not to your liking, best to keep both feet on the ground then.
