Thank you for looking. The shoes themselves are made of fabric mesh, so they are soft and do not choose the shape of your feet. Air in the sole. The insoles are fluffy and have low-rebound cushioning for walking shoes. There is a zipper on the inside for putting them on and taking them off. The sole height is about 3cm. They were worn outside about twice, but have been stored at home for a long time, so there are some dirt, cracks, etc. Please check the photos. This is a used item, so please only purchase if you understand this. Size: 23.5cm
