Thank you for viewing. Model Year: 22-23 Model, Authentic Brand: Head Size: 24.5-25.5cm Gender: Girls/Boys, Unisex Snowboard Boots, Kids, Black, BOA System The BOA system makes it very easy to put on and take off, making it perfect for children who are wearing boots for the first time! By inserting and removing the insole in the attached photo, it can accommodate sizes from 24.5cm to 25.5cm. (Insert the white insole first; it's 24.5cm with it in.) I bought these new last year for my child who started snowboarding. (Retail price around ¥16,000) They've been outgrown after one season (8 uses), so I'm selling them. I think they are clean as they haven't been used much, but there are some scratches from use. Please understand that these are used items. Also, they are listed on other sites. Please forgive me if they sell out.
