Caldera 8

We made this women’s trail-running shoe even better by listening to runner feedback. The Caldera 8 has plush cushioning for all-day comfort on the trails, plus improved fit, materialization, and comfort.

Sustainability

Running Responsibly

We are committed to a long-term, science-based approach to sustainability. We know it’s time to think bigger about the impact our products and their full life cycle have on people and the planet.

SUSTAINABILITY METRICS

Percentage of recycled content

• This metric refers to the percentage of material by weight that has been recycled from post- or pre-consumer sources.

Number of plastic bottles

• Our roadmap to use recycled raw materials initially focuses on post-consumer sources, such as plastic bottles.
• With help from our suppliers, we calculate the number of plastic bottles used to make a size medium of each product.
