Think! introduces Zeology-tanned leather shoes

In an industry where sustainability claims often blur into marketing slogans, footwear brand Think! is taking concrete steps to set itself apart. The Austria-based company, known for its European craftsmanship and commitment to responsible production, has partnered with German tannery Heinen to introduce a new standard in sustainable shoe materials.

Zeology at the core of the partnership

At the heart of this collaboration is Zeology-tanned leather, a material developed to eliminate long-standing environmental concerns in leather production. Unlike conventionally processed leather, Zeology leather is free from chrome, aldehyde, and heavy metals. It is also designed to be compostable under industrial conditions. Moreover, the tanning agent is certified through circular chemistry standards.

For Think!, the choice to work with Heinen and Zeology reflects more than material innovation. It marks a deliberate step toward aligning comfort, quality, and conscience in footwear design.

Sustainability that starts long before the first stitch

From raw hide to finished product, the partnership highlights how sustainability can be embedded at every stage of the supply chain. For consumers, it means footwear that not only feels good to wear, but also reduces environmental impact.

As the fashion industry continues to face scrutiny over its ecological footprint, the Think!–Heinen–Zeology alliance provides a tangible example of responsible innovation. Proudly showing that sustainable fashion begins long before the first stitch.
