Details

Introducing the Mello, a first-of-its-kind luxury sneaker that restores the planet—and biodegrades back into it. Handcrafted in Italy with Zeolite-tanned regenerative leather (meaning it's free from heavy metals), this Summit colorway is set on a lightweight and durable LACTAE HEVEA® sole that's handmade from responsibly sourced hevea-tree milk. The recycled corn, wool, and kenaf insole delivers cushioned comfort all day long.

The outsoles may differ in shades of 'cream' due to the different levels of carotene in hevea milk tree which is the natural property of a biodegradable sole.

  • Handmade in Tuscany, Italy
  • Constructed from Zeolite-tanned full-grain regenerative leather (Cow)
  • Partially lined with LWG-certified Italian leather (Cow)
  • Set on a 100% natural LACTAE HEVEA® sole
  • Tightly stitched for water resistance
  • Threaded with organic cotton laces
  • Fitted with a removable biodegradable insole (Corn, wool, kenaf)

      Sustainability

      Regenerative leather: Our regenerative leather is sourced from regenerative farms in the Swiss Alps. These farms are reviving Alpine ecosystems by reversing carbon emissions, restoring soils, and increasing biodiversity. Learn more here.

      Zeolite tanning: Zeolite tanning is an innovative and more environmentally friendly alternative to chrome tanning. It involves tanning the hides with minerals rather than chrome, aldehyde, and heavy metals.

      LACTAE HEVEA® sole: LACTAE HEVEA® soles are made in France using responsibly sourced milk from hevea trees. The entire process—from sourcing the milk to pouring it into molds—is completed by hand.

      Organic cotton: This sneaker's laces are certified organic, meaning the fibers are organically grown and manufactured without harmful chemical inputs.
      Biodegradable materials: This sneaker's upper, laces, insole, and sole are biodegradable.
