Cutting edge: Japanese paper art inspires a non-slip shoe

Scientists use kirigami techniques to create a sole with pop-up, high-friction spikes

The Japanese art of paper cutting and folding, or kirigami, has led to mind-bending 3D structures from 2D sheets, including spectacular pop-up designs. But now researchers have been getting to grips with the technique for a very down-to-earth reason: creating non-slip shoes.

Scientists have revealed they have developed a kirigami-inspired sole, where tiny spikes pop up from its surface as the shoe is bent during walking. The team found the spikes enhance grip, which could help prevent potentially fatal falls.
