Had a phone call this morning to pickup the orthotics.
Had my 1 hr in them this morning and then have to do another hour tonight.
Apparently so your knee joints get used to the weird angle of your feet while you wear them.
I'll see what happens. Hopefully they work reasonably quickly, but I'm quite happy if they don't work fast. Anything has to be better than walking with a bad limp.
Wouldn't miss C2S again. Thanks for all the comments.
