Thanks for asking! Our Sugar Zeffers are our most sustainable shoe yet - Every element of our shoe is bio-based or recycled.
Our sole material—lovingly named SweetFoam™—is made with carbon negative green EVA, which is derived from renewable sugarcane. We’re planning to roll out SweetFoam™ through our entire product portfolio, while also encouraging the entire footwear industry to follow our lead and bring this new technology into their process.
We used recycled polyester and plant-based microsuede on the exterior of the straps, then filled them with a cushy castor bean oil foam, while the anchors holding everything together are made from bio-based nylon.
