Jump boots will say on the box if they are jump boots, they usually have a flat sole. No grooves for traction. I know because I made the mistake. Luckily before I wore them. =u ) As for jungles vs. ICB's. I have no clue, I think it is a personal preference. Some like jungles because they keep your feet cool, others hate them, because they allow too much water in. Description of ICBs...black, leather, speedlace, 10-12" combat boot. Do a google search, and you will find a better description. I hope this helps.
