I noticed something strange whilst watching TTT my 4th time. In the scene where Gandalf is calling the lord of all horses by whistling I noticed what looked to be like tennis shoes with laces under his robes. I pointed this out to my nephew and he agreed that it was, indeed tennis shoes.
Can anyone tell me if this is so?
They do kinda look like tennis shoes there!

I have seen other shots, particularly riding, where he looks like he is wearing some flat white laced boots. I will keep my eye out!
ecurbh, do you have any of those costume portraits of Gandalf the White that show his feet?
