Amen to the brethren's don't even think about wearing hobnails advice.
I do, however, wear heal plates. The reason being that the heals wear out both quickly & at strange angles. I am a big guy, which is probably a factor.
Heal plates are a lot like wearing those shoes with the wheels built into the heal on smooth surfaces. For speaking to CW Roundtables or at schools in uniform I have a pair of modern brogans. An Olympic level figure skating performance on a freshly waxed foyer convinced me that nobody cared what kind of shoes I wore.
