Like Lazarus, this thread returns from the dead.

I started running again and decided to wear my Vibram Bikila's. First run (Sunday) was 2.2 miles---the only after-effect was calf soreness. Ran again after work yesterday (Tuesday), went 3 miles. Felt it in the calves during and after I finished, and of course, my calves hurt now. Also felt it a little in my right achilles but that was just post-run. I hope to get out on Thursday (3 miles) and Sunday (probably 3 miles or 3.25ish).

Any tips on increasing distance and remaining injury free? I plan on taking it easy and not running fast/far since I'm just getting back into running. I'm being conscientious about gently stretching my calves.

Also, would it make sense to switch up and wear traditional running shoes for longer runs until my lower legs adapt?

By the way, I've been wearing Vibrams for two years (long walks, around the house, etc).
