I recently did an episode where I was talking about the causes of black toenails in runners after long runs, and I got a lot of comments and questions about, "Well, what should I do?"

We did talk about a couple of different things during that episode, where I was telling you how to check and make sure that you have sufficient space at the end of the shoes, that your running shoes aren't just too small or how to make sure that if you do have a lot of room in the shoes or if it seems like they're big enough.

But if those two things are not your issue, then it's more likely that when you're swinging your foot through, during what we call the swing phase of gait.

Today on the Doc On The Run podcast, we're talking about the top three tips to avoid getting black toenails from your long runs.
