I used these a few times for water play in front of the entrance. I think I bought them about 1-2 years ago. Brand unknown. They've been in the shoe rack the whole time, so they're only slightly misshapen, and there are almost no scratches or stains. Size: Please refer to the 8th image. Total length: Approximately 25.5cm Inner length (inside the seams): Approximately 22.1cm My foot is actually 23cm and it slightly sticks out from the seams. I think it will fit inside the seams for those with a foot size of up to 22.5cm. Sole Heel height: Approximately 4.3cm Toe height: 2.7cm For packaging, I will put rolled-up paper inside the straps to prevent them from being crushed, and then put them in a cardboard box. The thick straps are soft and will hold your feet well.
