THE INNER SHOE
2025
Crafted from upcycled bicycle inner tubes sourced from local bike shops, the Inner Shoe is designed for walking comfortably on rocky beaches.
Using an innovative construction method, we preserve the natural integrity of the rubber—without
re-vulcanization, cutting, or harmful glues.
This process minimizes exposure to toxic particles while allowing you to enjoy the pure strength and flexibility of high-quality natural rubber. Durable, water-resistant, and eco-friendly, the Inner Shoe redefines sustainable footwear.
For this individual project for the IDE SuperGreen module, I decided to design a shoe using upcycled bicycle inner tubes. As a cyclist myself, I frequently noticed this waste material in bike shops. Bicycle inner tubes are made from natural pure rubber, which is non-biodegradable. My goal was to repurpose this material in its existing form, experiment with its unique structure, and build upon it.
