The Batman Black Smudge Grey Flip Flops are for walking around in 4 foot snow. No, that isn't correct. The Batman Black Smudge Grey Flip Flops are for astronauts and moon walking. That still doesn't sound quite right. The Batman Black Smudge Grey Flip Flops are for warm, awesome weather and for showing off one's love of DC Comics' Dark Knight! Bingo! That's perfect. With a black / grey / white color scheme and 'smudge' effect, these flippy floppies are for the relaxed Batman fan!
