Unfortunately I never really learnt to trust the iWalk2.0 so I actually never really used it but I think had I had the time to train a bit more the thing would have been of real help to me while I had my foot in cast. As it so happens I ended up twisting the knee of the other foot (without the cast, the one I was supposed to use for walking) and had to have an operation on it. So at the end I had to be still for weeks:-(. But that second accident had nothing to do with the iWalk2.0, just explaining why I never really then used it.
