These
boots were unusually comfortable from day one. Cannot yet judge long-term performance. I have put about 45 miles on them so far in fairly
rocky Northern New England terrain, including Mt. Washington, King Ravine, Baxter Peak, and Mt. Moriah. They have excellent grip and good support. (I can't comment on the
insoles. I use
Superfeet orange inserts. I do not bother to try the stock
insoles first any more.) I noticed that they scuffed up very quickly, but I have previously worn nubuck-type
boots, which don't show rock abrasion so readily. I had a hard time choosing among these
boots, the
Asolo TPS 520, and the
Scarpa Kailash GTX. All 3 had a very nice fit, although the
Scarpa seemed especially snug without being tight. I eventually chose the
Zamberlan Skill GT on the basis of (1) likely durability (far fewer sewn seams than the
Scarpa, and even the
Asolo has a 2-piece tongue) and (2) what seemed like better cushioning in the sole, less bottom-of-the-foot fatigue.
