Woodcast is a lightweight, biodegradable material made from wood and biopolymers, originally developed to replace plaster casts. The material, invented by the Finnish high-tech company Onbone, proved to be so versatile it is now used in a wide array of areas, including sports. Woodcast offers an easy-to-use method to make supports that are comfortable and so thin that they fit in shoes. Only a hairdryer or heat gun is needed to shape the splint, so it fits perfectly and optimally supports the injured area or the area that needs support. The material can also easily be removed or reshaped simply by warming it up again. The company has already developed a new type of ankle and wrist braces, but there is a vast array of other sporting aids that can be fabricated with the material.
