Navy synthetic resin sandals, size M, tread pattern sole. - Color: Navy - Size: M (25.0-25.5cm) - Material: Synthetic resin - Sole design: Tread pattern Thank you for viewing. I purchased these because I broke my foot, but the cast was too thick and my foot wouldn't fit, so I am selling them. I only tried putting my right foot in once indoors, and I haven't even walked around indoors.
