chancletear

To walk while wearing chancletas (flip-flops/sandals), with regional emphasis on different details: in Nicaragua, Cuba, Colombia, Venezuela, Chile, and Argentina it leans toward dragging one's feet while walking; in El Salvador, Nicaragua, Costa Rica, Cuba, Puerto Rico, and Peru it leans toward the tapping/slapping sound the sandals make.

• Se le oía chancletear por todo el pasillo. — You could hear him shuffling in his flip-flops all down the hallway.
• No chanclees así, vas a despertar a todos. — Don't shuffle around like that, you're going to wake everyone up.
• Iba chancleteando descalzo, digo, con las chancletas puestas. — He went along flip-flopping barefoot — I mean, with his sandals on.

Assuming chancletear always describes the same thing everywhere — the 'dragging feet' emphasis and the 'slapping sound' emphasis are both valid depending on the country, and either can be what a speaker means.
