Thank you for viewing. Purchased through TV shopping. Features round protrusions the size of golf balls on the finger area. The arch of the foot is also padded. It was introduced as being very good for relieving fatigue and promoting good posture and health. Size: 22.5-26cm Slight stain on the 9th photo. Overlap uses Velcro (adjustable tightness). Used a few times as indoor slippers. The fit is good and I'd like to use them, but my toes are narrow (more so than the belt crossing) and they slip out a bit... I think they're very good for stimulating the arch of the foot. If anyone would like to use them, I think someone with a foot size of around 24-25cm would be ideal. Thank you. I believe I purchased them for around 8,000 yen...
