Sorry about the Achilles. I ruptured mine (back leg) 4 years ago at about the same situation you have found yourself. It is a significant injury so it changes a lot moving forward. A lot of it will come as you get more confident with your heel is what I keep getting told because my swing speed is about 10 mph slower than it was before. Hope to hear how this lesson goes for you. I’m about to do the same thing this off-season. Good luck!
