I've been wearing 5.11 boots on duty for years.  My boot of choice was their Taclite line.  Since it was discontinued, I figured I'd give these a shot.  I was only able to make it through one shift wearing them.  By the end of my shift, I had dark, purple bruises all around my ankle bones caused by a hard piece of plastic that was digging in all day.  It felt like 5.11 forgot to put padding around the ankle supports.  Every other pair of 5.11's that I've owned have always had plenty of padding and were very comfortable.  That was not the case with these boots.  I'm just glad I didn't have to run after anyone that day because I would have just let them go to avoid further pain.
