Varial Mids

I currently have varial mids that I am having a hard time replacing. They are stiff as boards and great for my flat feet/bad ankles. They are the all black fake leather ones with orange inside and logo. They don't turn up very much when I google them, and I can't find them for sale anywhere. Has anyone worn these and know a comparable model or where I might be able to find some old stock? I can see why they were probably unpopular but they are perfect for me. Thanks.
