I've always taken care of maintenance like the soles, so I think there's little damage to the bottom. The rubber is almost in the same condition as when it was applied. I'm selling these because I haven't worn them in the last few years. Please check the photos for the condition. The size feels like 27.5-28.5 cm. Since shipping is free, I'm looking for buyers in Honshu who can pay immediately and confirm receipt. Thank you for your consideration.
