I'm a bad, flat-footed, under pronator, and wear the soles off my shoes faster than I can replace them. I think this is why my foot started hurting a few weeks ago (back in April already) and my ankle swells anytime I use it. Since I've had to take a little break, I've been busy obsessing over new shoes, strengthening my weak ankles and arches, and fixing running form. I went for a test run today (after 2 more weeks resting)...it's not really better, but the run didn't make it worse. I'll take that as a good sign.
