Yes my heels still touch the ground I often sit on the edge of my bed place my feet on stacked flip flops and press down to get my heel too touch the ground. The stacked flip flops give me around a 2" "platform" I guess. Hurts my ankles a little bit in the beginning but holy hell does it ever do I ever feel the stretch in my calves haha.
This exercise is idiotic and very foolish. I'm telling you: STAND UP EVERY DAY!!!
The physios don't know anything.
Put your folded socks under the front of your feet and stand up so it forces to push your feet up a little.
Remember: your range of motion in your ankles will be determined after his much you forced your feet up during this process. You will be in a world of hell after the cast are taken off after frame removal if you never forced your feet up every day.
Use the walker and try to lean forward towards the wall, stretching your calfs. In that way you force your ankles to adapt to the new length.
Sitting on the bed, especially with sandals on, will be devastating.
