After almost a week of phoning the orthotics department and getting nowhere - an appointment magically appeared from nowhere this morning...the woman was telling me that there were no appointments all week - and oh - one just dropped into her lap the more I complained!!!! LOL!!! - AND it was for the very same day!!!
Soooo - I have just got back now - the orthotist said DS has broken all records by going through his boots so fast!! He has ordered a new pair and is having a rubber strip fitted to the front to help stop the same thing happening again. He has also ordered them in different sizes as his feet are a whole size different....he HAD outgrown them in one foot - as I had suspected. (I wasn't allowed 2 pairs though!!! I asked if he could have some trainer boots as well - but he said he can only have one pair at a time!)
HOPEFULLY he will get them before we go on holiday in 2 weeks!
Thanks for all those of you who advised me on going back to the orthotist after only 6 weeks!!!
