This item appears to be well authenticated. It exists, it can be seen and this has gone on since 1836. Way more important, it was and is a well used shoe. It is also quite unreasonable that it was made by a human cobbler. Mouseskin and super fine stitching happens to be largely beyond us. Let alone wearing it out. The shoe itself infers a humanoid that is around two feet tall.. That happens to be plausible. We have had glimpses of such folk and they could easily live in our midst using basic tech. In short, that remains the best explanation. Any sign would also be mistaken for a child as well. Presume been able to block our seeing them as well and mind to mind comms
