I am the two
I just realised something wierd. In the begining when Neo is in the train station his clothes are different. They're not all the way down to his heels, they're just beneath his knees. In the Neo/Smith fight scene his clothes extend down to his heels once again. I think the reason for this is because the train station is between the real world and the machine world, his clothes appear to be half real-half machine (world), if you know what I mean.
