Size: 23 cm I purchased these last summer when cleaning the pool. I've used them about 2-3 times and stored them after washing. There's no noticeable wear and tear on the heels, and I think they're in good condition. They are used items, but thank you for your understanding. I'm considering shipping via Yu-Packet Plus, and they will be compressed when the lid is closed, so please be aware of this. * Since the horizontal length of Yu-Packet Plus is 23.2 cm, if they don't fit in the box, I will ship them via Yu-Pack with simple packaging. These sandals are a combination of mesh and synthetic leather, providing excellent breathability. - Color: Black - Brand: biofitter - Design: Combination of mesh material and synthetic leather - Style: Sandals - Back strap: Adjustable Velcro strap Thank you for viewing.
