The size is 26.0cm. I've only worn them about 10 times since I bought them, so they're in pretty good condition. Of course, there are some minor scratches, but I think you can still use them for a long time. After cleaning off the dirt, I left them in their natural state without applying any cream. The insoles are almost new because I used other ones. The laces show some deterioration, possibly due to incompatibility with the eyelets. If you're concerned, you might want to replace them.
