These are zori sandals that belonged to my grandfather. They measure 26cm from end to end, but the actual foot size they fit might be a bit smaller. The soles are rubber. They were in a bag, seemingly unused, so there's no sign of wear like loose straps, but there are a few stains. This is a set of three pairs. They might be a bit too old to be considered Showa retro, but if you're interested, please take a look!
