I haven't actually found mine yet, but what i am trying to go with is a below knee height (roughly) with a smooth front, no laces. Buckles would be ok, but i'm having trouble finding some that would look "star warsy" What i would love in the end is to have the boot tops and shins to be sealed to the front of the boot, with the front being able to detach to allow the boot to be put on. A rough example of this would be most of the prequel jedi boots, they have a front that detaches, with the full length zip underneath. Good luck with your boot quest, let us know what you find
