This is more of a law enforcement type question, but I cannot post in COP TALK yet and I'm sure several EMS/Firefighters wear zip up boots. I bought a nice pair of Rocky zip up duty boots and they are extremely comfortable. My only problem, the zippers keep unzipping themselves causing a ton of aggravation. i work as a Deputy jailer and it drives me nuts because I'm constantly walking and I'm worried they'll come unzipped in an emergency situation. Are there any fast fixes for this? One of my former LEO friends said they used to use some type of Velcro strap under the zippers to keep them from sliding down. Thanks for the Help and all you EMS/FF do!!
