The present invention pertains to footwear where the tongue may be reversed in order to open and close vents in the upper of a shoe. Secondarily, the reversible tongue changes the aesthetics, coloration, indicia, or other appearance of the footwear. A shoe has an upper upon a sole. On the sides of the upper, generally vertical stripes have vent between them. The reversible tongue has a symmetric shape and it rotates upon a longitudinal axis. Placed within the upper upon a swivel, the tongue rotates to extend across the vents to close them and to retreat from the vents to open them. In rotating, the tongue changes the coloration, indicia, design, or other appearance aspects of the shoe. Rotation of the tongue occurs with shoe laces loosened or with removal of a foot from the shoe.
