Gel-Resolution All Court, 23cm Used for about a month on an omni court, but they didn't fit my feet, so I didn't use them for tennis. After that, I used them a few times on a grass field. The sole pattern is still in good condition with little wear. There is some fraying on the inside of the heel (right foot), but otherwise, the inside is in clean condition. Overall, the condition is clean, but please understand that these are used items.
