had some made after suffering with compartment syndrome in my shins whilst running. my leg would feel as hard as wood and I had a lump that came up everytime which was basically a tear.
had some orthotics made up and it sorted itself out. They werent the comfiest of things though as they were made from a very high density foam and were made pretty rigid. I started getting a lump on my instep from pressure so stopped using them. Then a couple of years ago I had some more made. These are made out of a lower density foam and are cut away to allow a bit of flex. They’re great and I put them in all my shoes now, although I find I dont need to use them on the bike
