Design Intent

"We spent 47 iterations getting the midsole right. Not because we are perfectionists for the sake of it, but because I have run in shoes that felt great for 200km and fell apart at 400. I wanted to build something that earns trust over distance, not just in the first week."

Prototype Iterations

These figures come from development testing of the Zitanos 2.0 with our manufacturing partner, across road, track and light trail. The first production run is being funded through Kickstarter. We will publish full production testing and material certifications in our first responsibility report.

Environmental Data

Carbon Footprint
Assessment in progress

We are committing to a full lifecycle assessment of the Zitanos 2.0 ahead of the first production run, and we will publish the verified figure here. We would rather show you a real, independently checked number than an estimate. You can read where we stand on our Sustainability and Ethics page. A repair and take-back programme is planned to launch alongside the shoe.
