I've been running in zero drop shoes for years (the influence of reading Born to Run just as I stated to like running) and it took about 3 weeks for the calves to stop aching. If I run to work more and then put on work shoes with heels I feel like I'm tiping forward for the first half an hour!
knees already feel the benefit - but yeah was guessing it's a few weeks of adjustment. I'm not striking on forefoot, much more mid foot - but still feels good.
