Tread & Butter insoles are made with natural cork harvested sustainably from the fabled cork oak trees in Portugal.
Meaning, the 'cork forests' in Portugal, are a special place. The trees provide a renewable resource and serve as giant carbon sink cluster. The cork is harvested (think of cork harvesting like picking an orange, it doesn't hurt the tree, it's actually good for the tree). That's good news because the cork forests in Portugal offset 10 million tons of carbon dioxide each year.
More on cork ... we use natural cork in our insoles in place of petroleum-based plastic or EVA that are commonly used by other brands. Tread & Butter insoles are handcrafted in Portugal.
Tread & Butter insoles feature XSTATIC® silver ion technology that kills bacteria & crushes odor to help keep your feet fresh & clean. XSTATIC is bluesign® approved, the highest standard in sustainable textile production.
Our packaging is everything you need and nothing you don't want. Light, efficient, resusable and so good looking.
