Scarpa Liskamm GTX
Historic Range: $274.95-$369.00
I have wore the Liskamms for 4 seasons guiding now. I have not had a bit of trouble with them. They still feel like the day I brought them.
A few friend claim them to be cold late season (November) but I disagree with them. Sure they might be a bit chilly, but nothing unbearable.
If you are looking for a serious mountaineering boot you can't go wrong with the Liskamm.
