I cannot find a thing about this model lol.
Maybe the classic Sk8 mid?
I know a lot of shoe names were shortened, some cutting out the wrong word, for a time.
The low, mid and hi referring to the Sk8 low, Sk8 mid and Sk8 hi among others.
There have been so many mid versions of regular shoes that have come and gone so quickly though, like the 112 mid, also the TNT mids of various styles, in particular the II and the V which I still have, as well as some others I boxes I cannot even remember unless I pull them out.
