At this stage it would be good to go for an X-ray to know the extent of healing. If your fracture has healed completely you can go ahead without the boot or else you have to continue with the boot.
Stiffness will decrease slowly over a period of time with physiotherapy.
Do not put undue pressure on your fractured leg.
Obviously, not what I wanted to hear. However it makes sense. I will continue with the boot until I go back to doc on 9/1. Thanks
