"Italian boots, enough said. If you want to give your feet love, go Italian."
Okay, I'm biased. I been buying Scarpa since 1990. They feel great and they are made for mountaineering. I'm planning a jmt this june and wanted a pair of lightweight mou taineering boots (crampon compatible). They are waterproof and light as well. Keep in mind that crampon compatible boots make all the difference when dealing with icy conditons. Safety is number one and so is swift ascents on crunchy early morning snow. May the crust be with you.
"This is the best boots for mountaineering. Really."
I've been using these for a long time, I think 5 years. They are rigid and good with crampons on, nice rubber and front stiffness for climbing. With some practice you can easily do 5.9 routes. They are great as summer boots on glaciers etc. and perfect for spring/autumn boots. Also, I've used them quite a lot in the winter, say maybe down to -10C. A pair of those handy warmers are good to have, just in case. These are durable and you will enjoy these for many years.
