If you want to work the catwalk, not just walk down it, then you need to concentrate on your model feet, and moving them in the model way - which is not the ordinary way!

What you need to do is of course walk with one foot in front of the other, in a straight line. Make an exaggerated movement so that you draw a straight line with your feet from where you start to where you end on the catwalk or runway.

Place your toes so that they face forwards too, and you will get that style that models have automatically.

Remember to place your feet down ball first which most don't do naturally.
