That sounds rather specific. You can self refer to your local NHS podiatry and you can get personalized insoles via the NHS.
I’d recommend visiting your GP and getting them to refer you to a physio for assessment if thats a ‘self assessment via Google’ you’ve given yourself – your feet are rather serious and it’s worth getting the proper trained opinion if you have not done so already.
You also, generally speaking, don’t want to roll your foot inwards – it causes your ankle to work at weird angles and can be the cause of all sorts of back and neck issues which can be quite serious. (Which is why I question your assessment)
