Three interpretations of the style known as the service boot:
The Wolverines, with their leather soles, are probably the "dressiest" of the three; the color works in their favor for that too. The Beans are the most work boot-like, and I find it a little odd that they don't have any speed hooks. The Fryes split the difference with a welt that matches both the leather and the sole; I wore them with wool trousers and a tweed sportcoat last Friday night.
I still wear my Caterpillar work boots more than any of these, probably because they are made for walking and standing, and they are the easiest to put on and take off.
