Not gonna wear logger boots though.

This feeling is shared by many climbers that I see posting. But like Boston Bull has said, it is hard to judge unless you have tried it. There is a reason spur boots such as Whites, Wescos, were developed. It is part of the overall setup. The steel-reinforced arch, the heel plate, and extra leather in the wear points are all designed to enhance comfort and efficiency when using spurs in the tree.
You can "make do" with almost anything but most would be surprised just how comfortable spur work can be with the properly fitted equipment.
