If you do then ignore this but I wish I'd been told this when first given orthoses. Thanks to a high instep, many shoes already didn't fit me properly/where uncomfortable on the bones of my instep so when I was prescribed custom orthoses for collapsing arches thanks to me eds, I found the increased height they gave my feet mean that pretty much no shoe fitted me and any that did where really tight at the top while still slipping at the heel. I asked for advice from the therapist fitting them and was pretty much told there was nothing they could do and I could wear them or not wear them. Anyway I later found out you can thread your laces in different ways for different feet! If you cross them they'll be tighter or if you just thread them at the sides they are looser so now I leave a gap in the middle at the bottom of my foot at only cross them at the top.
There's a image here that explains what I mean tho I can't speak for how well it addresses these particular concerns, just that I saw a similar diagram and worked out the best way for me by making certain bits tighter and some looser. external-content.duckduckgo...
