Only used once for a presentation, but there is a scratch on the heel of the right shoe (see photo 2). Other than that, there are no major stains. It fastens with Velcro, so it's easy to adjust. Chinese size 40. With an insole inserted, it fit my daughter perfectly, who usually wears 24cm shoes. I will ship it with the insole I bought from a 100-yen shop still inside.
