These reef boots were only tried on once at the beach break, so they're almost new. They're soft and light, designed for warm water. I think the thickness is about 1.5mm. The sole is a bit thicker and sturdy. My surf trip was canceled, and they've been stored away for a long time. My shoe size is about 24.5cm. For heeled sandals and pumps, I wear 24-23.5cm. There's a measurement of my foot in image 8. The length is a perfect fit for me, so it might be tight for someone with a larger foot. *The size on image 7 says 25-26cm, but when I bought them, I was told that the reef boot sizing runs large. *I'd like to ship them in a Rakuraku Mercari Compact BOX, so if you need the box, I'll fold it to fit. (I think it will fit, but if it doesn't, I'm sorry!)
