Am I missing something about Orianna

Last night I was playing a game and got absolutely rolled by an Orianna. After I died due to not being able to run away, even with flash, I clicked on her character and she had 30 more movement speed than me, I was playing Lux btw, and we both had just brown boots and no other movement speed enhancement. I checked her runes after the game, no move speed Quints and no masteries that boosted movement. Am I missing something about Orianna's kit that gives move speed? Or could it be something else? Oh also this was before any drakes were taken, so she did not have a Cloud Drake.
