The captivating combination of suede and smooth calfskin transforms these women's trainers from the French label O.T.A. into a casual leisure wear companion that does more than just make a visual statement. The soles are made from recycled car tires in a process that is ethical, sustainable, and environmentally friendly, making each model unique. An additional design element can also be found on the heel – the coordinates there refer to Glencoe, the place that gives the shoe its name.
