I purchased these in excellent condition a while ago and have been storing them in the shoe cabinet. Size 6.5 (25cm) There's something that looks like mold on the sides. I've cleaned them at home. Also, there's some fraying. I think you can see both in the pictures. There's reinforcing fabric on both sides. The rubber isn't stiff for its age. That's just my impression. The color is lighter than the red in the pictures. The last picture is closer to the actual color. Thank you for your understanding.
