Tested my theory a little about the Saucony Peregrine 3s being the source of my right lateral heel pain. Ran the cross country team's home course; a pretty technical route with some short but steep hills but did so in my Nike racing flats.
Yep, no heel pain. Granted it was short, but it gave me a better idea that it was the Saucony's. Will continue to stick with mostly roads for now but when on trails, will wear the flats.
Hopefully will do another step-up tomorrow, something around five miles.
Ran 3.1 miles @ 9:12/mile pace.
