Well, Boba Fettish, since you brought it up....
Brak's threw out the idea that Fett's gloves resemble BMX gloves in style. And since they did use the BMX shoulder pad for the Sandtroopers I thought it was looking in to. I did a little searching on vintage BMX gloves and found this pic:

While it doesn't give us much, the look is similar.
While BMX gloves are similar in style with the padded white fingers, there NO concrete evidence as of yet that confirms this. Right now it is one of the miriad of possibilities. Perhaps they were parade gloves inspired by a BMX design?
