Merrell Ventilators for day to day stuff. I used to work at REI so having the entire clothing department help me out on selecting footwear was nice. I have some issues from wearing boots all the time and when not on duty, really needed a boot with good airflow. The Ventilators win there. For work, Danner Kinetics in black, 8". In the academy some of my classmates (including multi-war veterans) generally called them my Ninja Boots because they were so quiet I kept unintentionally sneaking up on guys and scaring the shit out of them (bad idea when it's a 3-Iraq tour Ranger......). On my 2nd pair (first has not worn out yet) just to give them both a break. I have the older "shiny" (daytime patrol) pair as a backup and my shiny-but-not-as-much nighttime patrol pair.
