Pick Up Your Feet

What is it with the walking feet shufflers?   Are we so out of shape that we can't pick up our feet walking down Market Street?  Those of you that shuffle down the sidewalk don’t appear to me that you can afford a new pair of shoes every month. It isn't just one group, every make and model has foot shufflers.  I watched, and listened, to a woman in a business outfit wearing flat shoes (which wasn’t right to start) shuffling down the sidewalk.  At first I thought maybe her shoes were too big but that wasn’t the case.  How does that scooting along the sidewalk sound go?  I should walk behind one of them and record the sound someday.
