These are the rare 610s from Japan. I think the women's sizes are especially scarce. There was a hole on the inside of the right ankle due to rubbing, so it has been sewn and repaired. The location and color make it almost unnoticeable when worn normally. No box. Please ask any questions you may have in the comments!
