I have had them all, from the ultra cheap to the ultra pricey.  This is the most comfortable and durable boot I have found at any price point.

The Comfort Core orthotic insert is amazing.  My feet stay comfortable until I take the boots off.  I can stand all day long, carry heavy loads, walk on uneven construction sites and not feel fatigue or theweight of my person or my load being tranferred to my heels.  The fabric inside is comfortable and has become like a sock over my sox.

The leather is a high quality and resists abrasions.  There is triple stitching all over the place and the eyes and hooks are well made.  The loop at the back aids in getting a foot into the boot.

The sole is heavy duty.  These have not left scuff marks on any surface.  They grip well and help me feel sure footed on every surface.  The wear of the soles is lasting longer than expected.

The waterproof feature is helpful.  Though I have not worn these in soaking rain I would not hesitate to get them wet.

Overall I would say these are very fine boots.  After another 2 years I am not sure if I will get them resoled or just buy a new pair.
