The SSP Facebook page (see also the Links page under About>Resources>Links) features several videos showing the special relationship between humans and footwear.  For example the effect of new red dancing shoes on the dancer in the YouTube video Tanzschule is shown beautifully.  We are left to imagine what the dancer is thinking and feeling.  The same may be said for the Seated Dancer in an old Roman statuette from the late third or early fourth century A.D.
