The Merrell Moab Mid boots with Gore-Tex are a fine $100 light hiking boot.

They have a quality construction, a nice grippy sole, and are quite breathable.  What they are not is a backpacking boot.  The ankle support of the mid is no greater than that of the low, what the mid offers is the ability to walk through deeper water than the low.  While they are lighter than a proper backpacking boot they are not as light as even the taller trail-runners.

The lacing system is adequate, but not the most durable.  If you are one to sit cross legged on the ground you will eventually bend the stamped speed laces.  The lacing system is also difficult to segment.  If you prefer tightening the foot more than the ankle (or vise versa) these boots are not for you.

The upper material, while quite breathable and surprisingly resistant to abrasion, is difficult to clean.  I would suggest not wearing these in clay muds.
