Best insert for supination?

I’m thinking some of my knee issues may be due to supination with my foot/ankle and a lack of engagement of my VMO. I want to try some inserts or corrective orthotics. Does anyone have a recommendation? I’m thinking of first getting good arch support, but then possibly trying probably a heel wedge (thickness on the outside) or something similar. I ride SPDs mostly so I think I’d rather not wedge my cleat unless I have to.
