I wouldn't think so. I used sorbothanes in my boots and pussers white pumps which had all the shock absorption of a plank of wood. I think you have 'pro-boots' now (sounds like that's what you've picked up) which are much better for running than the old high leg combat boot. I think they have a vibram sole and seemed to have arch supports and all that stuff already.Do PTI's have any problems with us wearing insoles?
I posted some lower leg exercises on the 'Sneaky' thread in the special forces section - way off topic but what the hell? They might help and there's no impact involved. If you can't run then row, cycle, swim - preferably with your boots on - the latter isn't as easy as it sounds


That would have been it muckerthen again maybe that was just from your offer of a drink
