I've only worn these indoors, but as you can see in the photos, there are some areas with minor stains. The sole says "17," but there's no size indication. Measuring the sole with a tape measure, it's 15cm. I believe the size is around 14cm to 15cm. Please be aware of this. These were light-up sandals, but they didn't light up when I checked them, so please note that. I plan to lightly compress them for shipping. The shape may be altered during shipping, so please understand this.
