I just returned from a visit to my sports medicine doc with the go-ahead to start transitioning out of the walking boot. Tomorrow I'll wear it 75% of my waking hours, the next day 50%, the next day 25%, then I'm done with it. I've also been given the okay to do some swimming and light (low gear) cycling (on the indoor trainer). While it's not running, at least I'll be able to remind myself what an increased heart rate feels like. I've enjoyed doing strength training, but I've been jonesing for an endorphin fix lately. Not sure I'll get that fix from light spinning and getting lapped by old ladies at the pool, but it's definitely better than nothing!
As I transition away from the boot, I'll be breaking in my orthotics, then will wear them pretty much full-time. I'll visit the doc again on January 1st. At that point, I'll start specific strengthening exercises for my foot (feet), then, at some point, gradually start running. It'll be a long, slow process, but I'm game.
