I've just gotten home from a nice long barefoot walk at the park and now the soles of my feet are pretty dirty! I like to take my shoes off when I'm walking on the grass so that I can feel the earth beneath my feet and because it's winter here, the grass was a little wet and muddy. My soles are all wrinkled up and there's even a chunk of mud stuck to one of them! I rub my feet together, scrunch them up and spread my toes as wide as they can go and bring them up super close, lightly running my hands along my dirty muddy soles.
