I bought a pair of Imogene's for the start of my SOBO hike after deciding to go the trail runner route. After some research, I figured about 500-600 miles per pair was to be expected. I however blew them out and wore them down a little after 300 miles. I wasn't happy about the performance, so called their customer service to see what they thought or would do. Unlike most manufacturers, they weren't interested in catering to thru hikers and told me that what I experienced was normal wear and tear. Now I agree that it was standard wear and tear damage, it happened much faster than their competitor's options and that is what I wasn't satisfied with. The rep said that she honestly was "surprised" and "amazed" that they lasted as long as they did. To me, that would be like a car company saying they were impressed that you drove their car all of 75,000 miles in this day and age. If you want good mileage per dollar on trail runners, I don't think La Sportiva is the option you want to go with. I was pretty bummed since I went with them because I love the quality of their rock climbing shoes and expected the same in a trail runner. That's my two cents.
