Sneakergirl Princess crushes little plastic toy houses outside on a forest track. For this she is wearing her flip flops with paper-thin leather soles. Do you know the benefits of flip flops used for crushing? Yes of course you do. The sensitive bare soles get a perfect shelter - but all foot actions and movements can be watched in detail - by you! And believe - all these crushed and flattened houses can testify - flip-flopped feet are - extremely destructive!
