I have a pair of WESCO lineman's boots that are 12 years old. They are from the same area and made the same way. These are the boot of choice for climbing poles.

The heel is there to allow a deep pocket in the arch area for the gaff (pole climber) stirrup a solid place to grip the boot. It is also good for climbing extension ladders.

They weigh a ton, but I promise they do the job they were designed for. As an added benefit, the leather is almost cut/penetration proof. Can you say snake bite prevention???
