Sustainable, Eco-Friendly & made from as much recyclable material as earthly possible! These trainers not only look great but are so great for your conscience too. The G-Marathon Eco-Suede R PET is made from vegan leather and vegan suede. The laces and the seams are made from plastic bottles and the inside sole is made from squidgy cork. An amalgamation of waste products has been well and truly transformed into a wearable, desirable, special shoe. No detail has been missed and they are so well made that you would question ever going back to your old trainer ways.
