These are special sandals and a non-woven fabric bag to be worn for the protection of the Borobudur Temple ruins during a visit in 2025. They were only worn during the visit. The size is EU 35. As my foot size is 22.5-23cm, I chose the smallest size. The rubber sole is about 1.2cm thick. I would appreciate it if those who understand that this is a used item would consider purchasing it.
