First, walk around in your new minimalist or minimalist-inspired shoes during the two weeks you’re doing the daily prep exercises above. Next, gently run in them once during your first week, twice a week for the next two weeks, and three times the following week. Still feeling good? Ramp up the frequency and intensity of your runs. If at any time you experience pain, go back to square one: you might need to work more on your form or get a shoe with more cushioning—or both.
