Were you able to get physio for toe walking? If so what was the extent of the toe walking? Was it just when barefoot or when wearing shoes as well. Was it just sometimes or pretty much all of the time?
I used to toe walk (undiagnosed but I think I'm dyspraxic). I used to actually feel quite tight in the muscles at the backs of the legs in the morning, it loosened during the day. I wonder if pysio could help?
