the sneaker world has long been dominated by big brands, so, polish design students barbara motylińska and zuza gronwicz set out to propose an alternative, more sustainable model for the production and distribution of footwear. with around 20 billion pairs of shoes produced each year, and 300 million pairs thrown out annually, the duo set out to create a sustainable production chain that wouldn’t do quite so much damage to our planet, using 3D-printing techniques.

with their ‘shoetopia’ project, motylińska and gronwicz created an design for a biodegradable sneaker, that can be modified via an app. the personalized design is then transformed into a print file, which can be sent directly to a local 3D printing center or private printer owner. the concept reinvents the wheel by reducing waste due to over production, and puts the customer in the driving seat by letting them request exactly the design they want.

the prototype shoe is constructed from flexible, biodegradable filament and natural textiles. in the search for a way of strengthening the textile upper, the duo cracked how to directly 3D print the filament onto the material. in turn, the technique meant the whole shoe design can be constructed without even using glue, making it both more environmentally friendly and durable.

the prototype design is transferred into a preset algorithm, meaning that anyone can design and customize it without having special shoemaking skills. the online design wizard even comes with a foot measuring application, meaning the shoes are printed to a perfect fit.
