Sports sandals with mesh material and adjustable straps. Size is M. I was able to wear them, and I am 24cm, but since M seems to be around 24-25cm, I chose the size 24.5. I've worn them outside for short periods a few times, so the number of times I've used them is small. I think there is almost no wear on the soles. They look clean at a glance, but they were stored at home and there are some minor details and stains, so I've marked them as "slightly dirty." Please understand that these are used items, including the above points. Thank you.
