I bought these for my daughter's speed training, but they were a little too big, and unfortunately, they didn't fit her foot well... ( ; ; ) Used only for a 6km pace run on a tartan track. As you can see in the photos, there's a little bit of tartan track dirt on the outside of the right shoe. They haven't been worn much, so there's no wear and tear. Thank you. #Adizero #JAPAN9 #24.5
