Running in heels seems like it'd be dangerous. I get Haida seems to be wearing them every day so I guess she'd have a lot of practice. But considering how unlucky she can get, running in heels seems a bit reckless.
But Kuroi, brother, you don't get to go all drunken "isn't the world amazing ?" and NOT say a word about your girlfriend. Shyness is no excuse mate, you NEED to tell her she is the most amazing of them all ! That's the rule !
