Only tried on indoors. I bought these because I liked them, but they seem too big for my feet, which are 22.5cm. I usually choose a size larger for sneakers and slip-ons, but it seems the regular size fits for Converse slip-ons. They were stored in the box in a safe place with air conditioning. I bought these new from the store's warehouse, so there are no signs of dirt. Please refrain from purchasing if you are particular about them being brand new, as they have been stored at home.
