I've worn these about three times. My actual foot size is 24.5cm, and I wear 25.5cm or 26.0cm in New Balance 996. I've applied oil and maintained them, so I think the leather is also in a state of absorbing moisture. If you'd like, I can include shoe trees for an additional 440 yen when I ship them. I've included as many photos as possible, but please feel free to ask if there's anything else you're concerned about.
