Mello

The Mello in Summit Regenerative is a first-of-its-kind luxury sneaker that restores the planet—and biodegrades back into it. Handcrafted in Italy with Zeolite-tanned regenerative leather (free from heavy metals), this off-white colorway is anchored by a lightweight, durable LACTAE HEVEA® sole handmade from responsibly sourced hevea-tree milk. A recycled corn, wool, and kenaf insole provides cushioned comfort all day long, while natural variations in carotene levels lend each cream-colored outsole its unique character.

With its clean, modern silhouette and eco-conscious design, the Mello in Summit Regenerative pairs effortlessly with minimalist streetwear or elevated casual ensembles—perfect with slim-fit denim and a crisp tee or chinos and a lightweight jacket for a refined, sustainable statement.

Please note that regenerative leathers are uniquely textured and may have subtle markings, which highlight the beauty of a life spent grazing in the Alpine pastures.

• Before first wear (optional): Apply a light, even coat of our Eco Protect Spray from a distance—just a fine mist, not saturated. You can reapply every few weeks for extra protection.
• Cleaning: Brush off dry dirt and debris with a microfiber cloth. Skip traditional shoe cleaners—they can interfere with the leather’s natural properties.
• Water contact: Try to avoid water when possible, as it can cause discoloration. If water droplets do get on them, gently wipe away with a slightly damp cloth.
• Storage: Keep them in a cool, dry, dark place for long-term storage, as the leather can be sensitive to prolonged sunlight exposure.
