Leather Mountaineering Boots? in The Gear Critic Posted May 15, 2007 I've had a pair of Nepalis for years, taken them on multiple long expeditions, and the only thing I needed to replace was the sole b/c I wore the tread down and compressed it to the point where crampons wouldn't fit them. The leather up remains completely intact. I've replaced the shoe laces several times. The point is: $450 for a pair of boots that can last for years isn't such a bad deal.
