Meanwhile in Australia, students from Sydney University have developed a DIY-insole using mushroom spores to treat foot-related health issues at home.
The innovation comes in a simple kit, with a cardboard model for the base structure, quick-growing mushroom spawn, and microprocessors that are implanted into the insole.
Users can monitor their foot health by app, thanks to the electronic components, as well as engage in interactive foot exercises to prevent illness and injury.
The microprocessors can be reused; and the original sole composted.
A product that could gain a foothold in the industry.
