Back to school means something new, and always more grape and eco-responsibility!
This is our 3rd trainer style, and because you don't change a winning formula, we remain 100% vegan with the Alpha Bicolors. After all, it's in our DNA… If you don't know us yet, here's a reminder: Zèta is about transparency, comfort, responsible fashion, and… style, of course.
The Alpha Bicolors style: vegan trainers, crafted with taste!
As you will have gathered, this style is made from recycled, recyclable and vegan materials. It is a unisex lace-up trainer, crafted from grape marc, recycled rubber, recycled PET and recycled cork. They are assembled in the same way as the classic Alpha.
The composition
- The exterior of the shoe is made with innovative grape-based materials: a plant-based material produced from all the matter that remains after the harvest and cannot be used elsewhere.
- The outsole is made from recycled synthetic rubber (70%).
- The inner lining is made from recycled PET (material sourced from plastic bottles recovered from the Mediterranean).
- The insole, meanwhile, is always made from recycled cork (100%).
- And finally, as always, the packaging is made from recycled cardboard!
The colours
The ALPHA bicolour trainers are all about white, white and more white. Based on your feedback, it is the colour you loved most across our last 2 styles, so we thought we would treat you! We crafted 4 styles, all white, but with our own personal touch on the soles: pastel pink, sky blue, yellow, and camel.
