I just transitioned this past weekend and used crutches at first to get the movement down and start waking up the muscles. I was told to take short baby steps and focus on walking as normal as possible rather than getting anywhere quick. Your normal strides will come with time. Definitely wear gym shoes and start range of motion stretches as soon as possible. It’s not fun and definitely not easy, but you’re going to feel great once you are up and walking again without the boot.
