After having solved all of the world's problems like cancer and global warming, scientists turn their attention to the vexing problem of why the top of your shoes get soaked when walking on a wet pavement:
The team used a high-speed video camera to film a person walking on a wet floor. The footage (see above) reveals how water is flung up from the ground, along the sole, and onto the top of the shoe.
The researchers calculated that shoes flick up about a pint of water after walking 20 kilometres on a damp day.
