Size is 26cm. Purchased on July 25, 2025, from the Puma official online shop for my son in the track and field club, but he doesn't want to wear them because they're the same as his friend's, so I'm putting them up for sale. I removed the tags, but they are brand new and unused. If they don't sell, I (the father) will use them since I'm also a runner. No claims and no returns!
