ASICS Sukusuku Mycel 14.0 Used for about 3 months for outdoor play at daycare. I don't think the frequency of use or wearing time was that long. However, perhaps because they were worn on sand and dirt, there are some stains here and there that cannot be removed even with a sneaker cleaner. The insole has some noticeable adhesive residue on the heel part of the sticker. (New insoles can be purchased online for about 800 yen, so please let me know if you would prefer them without the insole.)
