The document discusses the climate, trees, and appropriate shoes for several cities. Manaus has a tropical wet climate and myrtaceae trees, where sandals can be worn in the dry season and shoes that protect from rain in the wet season. Brasilia also has a tropical wet and dry climate and flamboyant trees, allowing for both sandals and shoes. Natal has a semiarid climate and the largest cajueiro tree, making sandals better due to the warm weather.
