The Marana Michelin x TFTF is a limited edition that ties into etnies’ “Buy a Shoe, Plant a Tree” initiative with Trees For The Future (TFTF). It’s essentially the rugged Marana Michelin – featuring the 3× durable Michelin outsole and rubber toe cap – presented in a special eco-themed colorway. Sustainable materials like a portion of recycled polyester and an algae-based Bloom insole may be included (as with the Preserve line). Each pair supports tree planting efforts. It’s the same performance skate shoe, but with an environmental mission.
