Angelina I don't understand the question, too
If it comes to walking it's not so much about the length of a step but about the fact that you need to change how you move your body, like when you want to close your shoes, get up from the floor or if you pick something from the floor. As long as you don't rush things, walking is a bit slower but more or less easy. Running, like for catching a bus, is the problem.
