The UYN 3D Ribs shoe surprises with its lightness, comfort and functionality. The 3D Reverse(R) construction makes the upper stable and elastic. At the same time it prevents wrinkles and overlapping of material while walking or running. The inner layer is made of organically derived Natex fibre, which is particularly effective at wicking away perspiration and reducing unpleasant odours. The natural and breathable hemp sole makes the 3D Ribs shoe perfect for summer use.
