Comment: Was looking for shorter boot than either my 10" engineering boots and came across the Joe Rocket Big Bang 2.0 boots. Decided to take a chance on them, partly due to Jafrum's great return policy. Once they arrived, I quickly worked my huge feet into them and wore them around the house for a couple of hours.
Initially a little stiff in the sole, these boots loosed up after a day of walking around in them. Not uncomfortable, just a bit stiff. The ankle support is excellent, and the soles really grip the road when putting your foot down. After the first day of wearing them, they felt pretty good, and are about 90% of the way to be broken in.
One complaint is that the pulls on the back of the boot are a bit flimsy, and one broke on me the first time I put some pressure on it. And I will probably replace the laces with a zipper closure just to make putting them on a bit easier.
All in all, I really like these boots.
