Black sandals with straps, excellent safety with non-slip soles. - Color: Black - Size: 21 - Design features: With straps, non-slip sole They seemed very comfortable to wear, but I'm selling them because they're too small now. I bought them new and wore them for one season. There are no noticeable flaws, but please purchase only if you understand that they are used. Please note that they will likely be flattened for shipping. Thank you for looking.
