Thank you for viewing from among many items. The size is 25.5cm. As you can see in the photos, there is wear and tear on the soles and some scuffing. Although I frequently and easily washed them, there is still some remaining dirt. Please check the photos. I used these for jogging for about a year. Please note that there is no box. I plan to ship them in a simple package, with stuffing inside and placed in a plastic bag to make them as compact as possible. Please refrain from purchasing if you are concerned about the storage period. Please understand that these are reused items before purchasing. Immediate purchase is possible. I do not accept any price negotiations. The person who purchases first, even if they comment in the middle of a conversation, will be given priority. ***Please Read!*** I will cancel transactions with those who have previously requested to bundle items and then did not purchase them. I have had several uneasy transactions where there were no comments after the product arrived, and no receipt evaluations were made. Therefore, after purchase, I would appreciate it if you could please comment after your purchase. If you are paying at a convenience store, please let me know your expected payment date. *** *** *** *** ***
