Avoid Asolo. The foam they use to attach the sole degrades even without use. I have a set that was only about 10 years old but lightly used and which sat for a few years when I didn't do much hiking. When I took them out, not even 1/2 mile into a trail the sole started flapping loose. Apparently it's a very common problem. I had them resoled with a Vibram sole because the upper is so comfortable but it was tough even finding someone to work on them.
