I should have asked for a pirate leg in the beginning

Please do read the article above on Leg Length Differential. Tap the title in blue and the article will unfurl. I’m not sure where you got the shoe insert, but you really do need to get your leg measured by a professional. I’d advise you look into this so you don’t further compromise your knee since you mentioned it’s bothering you.
Best of luck to you and a Happy New Year too!
