While these may look like something a very bored fan would come up with in their spare time, they are real. Made by Reebok and officially licensed.
No release info or pricing yet, but they will surely be limited and fairly expensive.
I... kinda want a pair. Not to wear out. Just to wear around the house, running around making whooshing and "pew pew" noises while I kick things pretending they're evil spaceships.
