SPN-TEC

‘SPN-TEC’ is a collection of 100% recyclable shoes that challenges the visual stereotypes of sustainable design, building on my previous project, ‘PIN-TEC’. Traditional shoes consist of 62 individual panels glued, sewn, or nailed together, making them difficult to recycle. In contrast, ‘SPN-TEC’ shoes are entirely digitally designed and constructed without glue, stitches, or material contamination, while still using familiar materials from everyday footwear.

Each shoe is equipped with an NFC tag that serves as a digital passport, containing information on material origins, production waste, and 3D print files for repairs or alterations. This transparency allows users to access information typically kept secret by manufacturers, reinforcing ‘SPN-TEC’ as a fully transparent project.

The shoes are assembled using the ‘SPN-TEC’ module, which features a ratchet system and four cables connecting to a 3D-printed rubber outsole cage. This semi-flexible outsole wraps around spiky PU foam midsoles, ensuring a secure connection as the spikes protrude through cut-out holes in the cage. Some models use EVA uppers that are vacuum-formed and heat-welded, while a structure made from recycled soda bottles holds the shoe together and allows for adjustability.

The ‘SPN-TEC’ system introduces a digitally sculpted footwear collection that embodies zero material contamination, full recyclability, and complete transparency. Beyond sustainability, the collection also showcases visual appeal, harmonizing eco-consciousness with aesthetic design.
