These shoes were worn by my child at daycare and were rotated with four other pairs, brought home and washed weekly. The insoles are not removable. The tag is missing, so there's no size marking, but they were worn in conjunction with 14.5cm shoes. They are Skechers, so they were comfortable, and my child liked wearing them. Since they were worn by a child, there may be some sand, etc. Please refrain from purchasing if you are looking for a perfect item.
