It’s so much easier to recycle a shoe made from one kind of fabric than one that consists of more than 60 different parts. This realization inspired designer Ammo Liao to create the Bio-Knit shoe. To make the Bio-Knit shoe, one single material is processed in three different ways, all used in one shoe:
In the same way that paper can be both stiff cardboard or a flexible envelope, Liao can change the physical properties of polymer by heating it. Heat changes the stiffness of the threads, so he can create a semi-rigid heel, but also a soft, sock-like texture for the other parts. Ultimately, Liao wanted to create shoes that are environmentally friendly and easy to recycle.
