I wore these for about a year, from age 5 to 6, when I played futsal once a week in a gym. The Velcro is in good condition. The insoles have been replaced with others. (I replaced them to wash them.) There is no odor. There are some stains on the fabric in places, but they are not damaged, so they can still be worn. Please check the images and purchase if you understand. Shipping via Yu-packet Plus will cost around 500 yen, so please refrain from price negotiations.
