Sneakers tend to be a typical fast-fashion item and are often only worn for one season before they disappear into the depths of the wardrobe or are immediately thrown out. Compared to other articles of clothing, they are generally made of many different, glued-together components. That means they are difficult to recycle and present a huge environmental problem. The 3D SPHERE shoes prove that there is another way. This innovative shoe is produced from thermoplastic polyurethane in a 3D printing process. That makes it fully recyclable, as thermoplastics can repeatedly be melted down and turned into new products. The greatest challenge for the development of the 3D SPHERE was to deliver the complex functionality of a shoe, which has to fulfil a wide range of tasks, with only one material and one technology. Testing and fine-tuning the ideal fit and feel of the sole and shoe upper took a correspondingly long time. The result, however, is a lightweight sole with good cushioning properties and a surface structure that offers stability and support. 3D printing has the added benefit of being able to produce each shoe to order and to customise it using a 3D scan of the wearer’s feet. Buyers thus take home a pair of made-to-measure shoes whose futuristic look is bound to attract attention.
Statement by the Jury
The 3D SPHERE presents a concept for the future of the footwear industry. In an impressive way, it demonstrates the impact a technology such as 3D printing can have on our everyday life by democratising the made-to-measure production of shoes. 3D SPHERE skilfully capitalises on a production method that is still in its infancy, in order to combine functionality, minimal material consumption, ergonomics, customisation and sustainability in a shoe with a fascinating appearance.
