Koio | Retro Runner In Castagna Men’s Sneaker

The Retro Runner is a vintage-inspired silhouette modernized with cutting-edge, sustainable materials. Shown here in our beloved Castagna color, it has vegetable-tanned leather upper that develops a rich patina over time and is set on a Koio ReCycled sole that provides comfort and flexibility through every step.
