RaineRaine Inc. manufactures many products for law enforcement, military and other field uses. They offer boot zippers that convert laced boots to quick-entry zipper boots. These zippers provide the most adjustability and comfort available in tactical boots.  Raine also makes boot blousers that keep trousers in the desired position and secures the pants down to the boots neatly without bulk. The durable trouser blousers are also easy to use and allow for healthy circulation in the legs.
