For around $72.00, these are just all around great boots. I tried on some $125.00 Danner's and the comfort was no different then my Magnums. Ankle support is excellent. I actually find it difficult to roll my ankle in these boots. I do a lot of walking on various terrains here in Iraq and my Magnums have handled them all with no problems. There was no "break-in" period required. These boots were ready for work right out of the box. My only complaint is for a lack of speed laces. So far I haven't had a real need for them though. If you are looking for a great boot but don't want to spend a ton of money, look no further. These boots are probably the best boot you will find at this price.
*UPDATE*
I've had these boots for almost 8 months now and they are as good as new. I can walk around for hours and have no pain in my feet. I haven't rolled ankle yet! The wide sole at the heal makes it almost impossible to role your ankle. The constrution is holding together perfectly; the soles aren't peeling away, the stitching is still in tact. The only issue I had is with the laces, they broke after about 4 months but that was an easy fix with some new speed laces. I would recommend these boots to anyone.
