I have a pair of scarpa Kailash, and have had them for 5 years. I work in an industry where I'm hiking around a lot, and I also enjoy long backpacking trips/hikes. The first hike I ever took these on was a 70 km round trip and I got 0 blisters without breaking them in. I love these shoes, I got my boyfriend to buy himself a pair of the men's ,he loves them. They're a good shoe.
