Totally nerding out here...
I wondered what show the photo came from and cannot get a conclusive answer. It's from 2008, but nearly every show had a different dress, those purple boots, sandals in latin america or was in daylight. The guard and some hands looks latin, so that's my guess....
I have only seen her wear converse on 2 occasions: Coachella and the gig in the photo.
Could be the right show and a wristband can be seen.
The ad photo could very well been from this performance - but I cannot find any photo/video of footwear from this show. I think every other 2008 show can be ruled out.
