Pros: Full grain leather construction has proven very durable and fairly water resistant. Alloy safety toe and polyurethane mid-sole combine to yield a fairly light boot.  Very good ergonomic design results in a comfortable, supportive, stable, all-day boot.  I'm a project manager in the oi/gas industry and the out-sole is both slip and oil resistant.  Top hooks make donning boots quick and easy.  I've worn these boots daily for about 3 months and they seem to be wearing well.

Cons: I replaced the standard foot-beds with Sole custom foot-beds to help with over-pronation (my defect, not the boot's).  With custom foot-beds, these boots don't breath well on hot days.  The tread design is difficult to clean.  The uppers vary in dimension between left and right boot.

Summary:  Good water resistance usually means that a boot won't breath well - I think this is an acceptable trade-off.  If these boots hold up well for the next six months (my boots rarely last a year), I'll probably buy another pair.  I just wish the left-to-right sizing was more consistent.
