The Denver Boot was invented in 1953 for use by the Denver Police Department. Since that time, the Denver Boot has become the world's most renowned vehicle immobilization device. The important things to know are that it is light weight at 14 pounds (half the weight of most other boots), it does not rust or require paint and it is easy to install.

The boot is a three piece assembly: wheelclamp, hub (lug nut) cover, and arm. The arm has two pockets which allow for an adjustment for wheel size (larger or smaller). The three piece assembly allows for a compact device and is very easy to transport in multiples. When paint is requested, the hub cover and arm are painted for "higher visibility" purpose. As the boot does not rust, the paint is not required for protection. This is a cosmetic and often desired requirement.

As vehicles have changed since 1953, so has The Denver Boot, there are now 3 different types of boots. The Standard Boot - fits the majority of the vehicles on the road. The 4x4 Boot - is designed for vehicles with extended hub axle shafts, like Ford Explorer or Nissan Pathfinder. The Super Boot - is designed for "mega trucks" like F250 and F350 with oversized wheels and tires.
