Okay - here's a question for you.

 

I haven't done any barefoot track work since I was in college and didn't care, but is there a way to get the track stain out of your feet other than waiting for the skin to naturally recycle and flake off?

 

I've got me some black feet right now...

 

I'm hoping I can keep the wife from noticing and making me sleep in socks...

 

(On a side note, managed a 62 second barefoot 400m in the middle of my workout - my PR is 60 flat. I haven't been doing much in the way of speed work and am technically in recovery mode from my marathon and 50k last month.)

Distract the wife and she won't notice the feet.  I'll let you figure out how... 

I used to run on the local high school track here but they resurfaced it a while back and I have the same trouble with the nasty black staining. I stopped running there because of it. Anyway I use a heavy duty firm bristle scrub brush and soap for the tougher stuff like that.
