The air unit around the ball of the left foot's little toe is damaged, and I strongly feel the air cushioning when stepping. I believe the internal support structure of the air unit is broken, causing the air to remain inflated. There are no air leaks, and the cushioning remains, so it's recommended for those who want to try them on and play. However, since other parts could break at any time, excessive play is not recommended. This is for those who want to try out these expensive shoes (originally priced around 30,000 yen) lightly in a gym to see if they fit. The insoles have been removed. The size is 27cm.
