Product Details: Oklahoma City Thunder Quick Ankle Socks Nike NBA Player Issue, Size M (23cm-25cm) Brand New, Unused I purchased these once and tried them on, but the size didn't fit, so I'm selling them. Please feel free to ask if you have any questions. I'm also open to price negotiations. ~Product Description~ The vertical and horizontal lines on the forefoot utilize "NANOFRONT" technology from Teijin Frontier. NANOFRONT has a surface area several dozen times larger than regular fibers, and its fine irregularities create a large frictional force. This results in high grip performance. This specification is only used for player-issue socks.
