Back to school means new arrivals — and always more grape goodness 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 of what Zèta stands for: 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 trainers.
The composition
- The upper of the shoe is crafted from innovative grape-based materials: a plant-based material made from all the matter left over after the grape harvest that cannot be used elsewhere.
- The outer sole is made from recycled synthetic rubber (70%).
- The inner lining is made from recycled PET (material derived 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 Bicolors trainers are all about white, white and more white. Based on your feedback, it was the colour you loved most on our last 2 styles, so we decided to treat you! We created 4 styles, all white, but with our personal touch on the soles: pastel pink, sky blue, yellow, and camel.
