I just talked to a reporter from the NY Times about runners surgically removing their toenails so they don't have to deal with blackened toenails.
I think I've lost one toenail ever and that was from dropping something on it, so I'm clearly not aware of the extent of this problem.
Anyone out there done this themselves or know of anyone (what about pros?) doing this? Sounds like it may be a thing more for the ultra types.
