I bought these new a few years ago. The size is 24cm. I've only used them about 5 times, so there's almost no wear on the soles, and I think you can still use them for a long time! There is some discoloration on the side of the sole, as shown in photo 8. Please be sure to check the condition in the photos before purchasing. Please understand that these are used items before purchasing. I threw away the outer box, so I plan to pack them in a cardboard box with waterproof protection and ship them. I also have running wear and shoes for sale. I will offer a discount if you buy multiple items, so feel free to contact me ♪
