Vans Old Skool shoes

Worn max 3 times, mostly indoors as a change of shoes. Long standing in the closet without use. Inside both shoes it looks like the fabric has worn out, but it is not a defect or something torn or worn out, in both shoes on both sides they are the same, so I assume that it should be so. On the suede heel there are minimal scratches which I assume can be cleaned with suede products. I bought 4 years ago Sportland for 79.95 € (there is a check). If you need more pictures or have any clarifying questions, feel free to write!
