 Does anyone have any experience or thoughts (or review links) on these?

I can barely find any information on them at all and only 1 review from a source I have never seen before:

My physio recommended trying them but the fact that they do not even appear on the RW shoe finder and they only cost £40 online makes me a little hessitant.
