Running

I keep hurting the top of my left foot, and I don't know what to do about it.

Changing the type of lacing has definitely helped, but I swear it's a recurrent issue, like it might become chronic. It's not like I can leave my shoes unlaced, I feel like too loose is almost as bad as too tight.

God I'm getting annoyed by it. I can't do enough miles to improve because this keeps flaring up. It wasn't a problem before, I have no idea what started it.

Edit: to be honest my assumption is that it's extensor tendonitis.
