Purchased from the official NIKE online store. I'm selling these because the size didn't fit. I bought them in a different color and tried on the other pair, so these are still unopened. They are labeled as 25cm, but they run a bit small. I think they would be a good fit for someone who usually wears a 24cm or 24.5cm. This is just my personal opinion. Please refrain from purchasing if you are overly sensitive or likely to complain. They can be worn for both stylish and casual looks. I think they can be worn like beach sandals or Benassi slides.
