I just received the Lowa Khumba II GTX from Lathrop and Sons. I haven't got a chance to use them. My initial impressions are they are well made, and will be perfect for light to heavy loads. The boots have a tapered shank (5mm to 3mm).
I have wore them around the house, but I have just been to busy to really hike in them yet. They are non-insulated and 3.9lbs. They should work good for high country mule deer and chasing elk in September.
